Thumbs up? Map shows Europe’s hitchhiking landscape
Average waiting time for hitchhikers in Ireland: Less than 30 minutes. In southern Spain: More than 90 minutes.
- A popular means of transportation from the 1920s to the 1980s, hitchhiking has since fallen in disrepute.
- However, as this map shows, thumbing a ride still occupies a thriving niche – if at great geographic variance.
- In some countries and areas, you'll be off the street in no time. In other places, it's much harder to thumb your way from A to B.
Rated for hitchability
User-based tips and tricks on how to hitch a ride throughout Europe (and the rest of the world).
If you've never stuck out your thumb to get somewhere, nor picked up someone who did, you're now part of the overwhelming majority. Nevertheless, like vinyl, hitchhiking has survived the predictions of its demise and occupies a small but thriving niche.
There's an entire wiki dedicated to the practice, including a map detailing hitchhiking spots around the world, rating each for 'hitchability' and providing a user-generated average waiting time for each spot.
Based on that information, Abel Sulyok has produced this map, showing average waiting times across Europe as experienced by hitchhikers themselves. The map provides a curious overview of the continent's hitchhiking landscape, indicating where it's easier to hitch a ride, and where your thumb is going to be sore before you're picked up.

Hitchhiking success (or failure) doesn't just depend on your technique or appearance, also on your location.

In areas colored darkest green, you're off the street in 10 minutes or less. Lightest green: half an hour. Things turn yellowy in areas where you have to wait up to an hour and then change to red for times up to 90 minutes. If it's more, you're in a deep burgundy.
- Some countries seem more hitchhiker-friendly than others. According to this map, you'll have most luck sticking out your thumb in Ireland, the Netherlands, Belgium, Denmark, Albania and Romania – all mainly light green.
- In-between countries include the UK, France, Germany, Poland, Bulgaria, Macedonia and Turkey (among others).
- Worst countries to hitchhike, at least according to this map: Spain, Portugal, Italy, Croatia, Greece, Austria, Sweden.
- Border areas seem prone to hitchhiking problems, although curiously often just in one direction. Check the Russian-Belarus border, or the ones between Bosnia and Serbia, Greece and Turkey, or Austria and all points south.
- Urban rides can be more difficult to hitch; see the 'hot spots' covering Paris, Athens, Kiev and the Liverpool/Manchester area in northwest England. In big cities, motorists can always soothe their bad conscience thinking the next car will pick up that rain-soaked stranger.
- Red can also mean remote, as it certainly does in Scotland's furthest north, or the interior of northern Sweden and Norway.
- Other red zones are more difficult to explain. Why the generalized aversion to autostopistas in both southern Spain and southern Italy? Why is Germany's Frisian coast so atypically hostile to hitchhikers? And what makes the southern Swedes so unamenable to helping out their non-motorized fellow travelers?
As this map shows, your hitchhiking success depends not just on your presentability, but also on where you present yourself.
From freighthopping to hitchhiking

Hitchhiking has a long tradition in the U.S. Its direct ancestor was freighthopping. After the Civil War, if you were looking for work but without your own means of transportation, you'd hop on freight trains to travel long distances.
By 1911, the ranks of these hobos (1) had swelled to an estimated 700,000 – or about 0.75% of the entire U.S. population at the time.
While lots of people kept riding the rails throughout the 20th century (2), the rise of the automobile provided a much safer and more flexible means of hitching rides to faraway destinations.
Popular (and patriotic)
Hitchhiking (3) really took off after 1929, when the Depression both limited people's options to buy their own cars and increased their need to move around to find work. Under the New Deal, the US Government even set up a Transient Bureau that helped both hobos and hitchhikers.
Hitchhiking entered the national consciousness, portrayed in popular books (John Steinbeck's The Grapes of Wrath) and films (It Happened One Night, starring Clark Gable and Claudette Colbert).
By one estimate in 1937, at least one adult American male in 10 had hitched a ride at least once. A Gallup poll conducted during World War II, when fuel-rationing and car shortages were keeping hitching popular (and patriotic), indicated that nearly half of all Americans had picked up a hitchhiker.
Friendly traveler or vicious murderer?

However, there were problems with hitchhiking almost from the start. Early on, public opinion swung against aggressive hitchhikers, sometimes standing in the middle of the road, practically "demanding a ride". Reports of crimes – real or otherwise – committed by hitchhikers predisposed the public and the authorities against it.
After WWII, laws and law enforcement further discouraged the practice, as exemplified by these FBI posters, warning drivers against hitchhikers: They could be "a happy vacationer or an escaping criminal – a pleasant companion or a sex maniac – a friendly traveller or a vicious murderer."
In the 1970s and 1980s, a slew of highly publicized crimes involving hitchhikers (to name just one: the Santa Rosa Hitchhiker Murders, 1972-73) – and a few movies playing on the fears they generated (The Texas Chainsaw Massacre, 1974; The Hitcher, 1987) – helped end its heyday.
Unsuited to hitchhiking

Add to that the generalized sentiment nowadays that 'stranger' equals 'danger', and the demise of hitchhiking seems logical. From the 1920s right up to the 1980s, thumbing a ride was a fairly common way to get around. These days, it's the option of last resort.
But perhaps the main reasons for hitchhiking's decline have less to do with moral panic, more with fundamental changes in infrastructure. For one, there's the post-war rise of the Interstate Highway System: Bigger, faster roads that are unsuited to hitchhiking.
The biggest underlying factor may be the rise of car ownership. The percentage of US households without a car has steadily declined, from about 50% in 1941 to less than 10% today (4). If you have a car, you don't need to hitch a ride.

(1) A short dictionary of early 20th-century vagrancy. Hobo: someone traveling to look for work. (Term possibly derived from hoe-boy, i.e. 'farmhand', or an abbreviation of homeward bound). Tramp: someone traveling, but not looking for work. (From tramping, i.e. long-distance walking, as this was their main means of getting about). Bum: someone neither looking for work nor traveling. (From the German bummler, 'loafer').
(2) There are still enough hobos around to animate a National Hobo Convention, every August since 1900, in Britt, Iowa. Nevertheless, the lifestyle is definitely fading – see this article about The Last Great American Hobos.
(3) Curiously, the term is much older than the automobile. It describes the practice of 'horse-sharing' in the Old West. According to an article in the American Motorist in 1978, "One man would start walking while the second man rode the horse to a predetermined spot. He would hitch the horse to a tree and walk on. When the first man [arrived], he would take the horse and ride past the other man to another predetermined spot."
(4) In 2010, 91.1% of American households had at least one car. In 2015, that figure had dropped slightly to 90.9%. Trendwatchers attribute this first decline in decades to millennials in big cities preferring car 'usership' over car ownership. However, the U.S. Census figure for 2017 indicates car ownership has gone up again, to a record 91.2%.
"Deepfakes" and "cheap fakes" are becoming strikingly convincing — even ones generated on freely available apps.
- A writer named Magdalene Visaggio recently used FaceApp and Airbrush to generate convincing portraits of early U.S. presidents.
- "Deepfake" technology has improved drastically in recent years, and some countries are already experiencing how it can weaponized for political purposes.
- It's currently unknown whether it'll be possible to develop technology that can quickly and accurately determine whether a given video is real or fake.
After former U.S. President William Henry Harrison delivered his inaugural speech on March 4, 1841, he posed for a daguerreotype, the first widely available photographic technology. It became the first photo taken of a sitting American president.
As for the eight presidents before Harrison, history can see them only through artistic renderings. (The exception is a handful of surviving daguerreotypes of John Quincy Adams, taken after he left office. In his diary, Adams described them as "hideous" and "too true to the original.")
But a recent project offers a glimpse of what early presidents might've looked like if photographed through modern cameras. Using FaceApp and Airbrush, Magdalene Visaggio, author of books such as "Eternity Girl" and "Kim & Kim," generated a collection of convincing portraits of the nation's first presidents, from George Washington to Ulysses S. Grant.

What might be surprising is that Visaggio was able to generate the images without a background in graphic design, using freely available tools. She wrote on Twitter:
"A lot of people think I'm a digital artist or whatever, so let me clarify how I work. Everything you see here is done in Faceapp+Airbrush on my phone. On the outside, each takes between 15-30 mins. Washington was a pretty simple one-and-done replacement."

Of course, Visaggio isn't the first person to create deepfakes (or "cheap fakes") of politicians.
In 2017, many people got their first glimpse of the technology through a video depicting former President Barack Obama warning: "We're entering an era in which our enemies can make it look like anyone is saying anything at any point in time." The video quickly reveals itself to be fake, with comedian Jordan Peele speaking for the computer-generated Obama.
While deepfakes haven't yet caused significant chaos in the U.S., incidents in other nations may offer clues of what's to come.
The future of deepfakes
In 2018, Gabon's president Ali Bongo had been out of the country for months receiving medical treatment. After Bongo hadn't been seen in public for months, rumors began swirling about his condition. Some suggested Bongo might even be dead. In response, Bongo's administration released a video that seemed to show the president addressing the nation.
But the video is strange, appearing choppy and blurry in parts. After political opponents declared the video to be a deepfake, Gabon's military attempted an unsuccessful coup. What's striking about the story is that, to this day, experts in the field of deepfakes can't conclusively verify whether the video was real.
The uncertainty and confusion generated by deepfakes poses a "global problem," according to a 2020 report from The Brookings Institution. In 2018, the U.S. Department of Defense released some of the first tools able to successfully detect deepfake videos. The problem, however, is that deepfake technology keeps improving, meaning forensic approaches may forever be one step behind the most sophisticated forms of deepfakes.
As the 2020 report noted, even if the private sector or governments create technology to identify deepfakes, they will:
"...operate more slowly than the generation of these fakes, allowing false representations to dominate the media landscape for days or even weeks. "A lie can go halfway around the world before the truth can get its shoes on," warns David Doermann, the director of the Artificial Intelligence Institute at the University of Buffalo. And if defensive methods yield results short of certainty, as many will, technology companies will be hesitant to label the likely misrepresentations as fakes."
Ancient corridors below the French capital have served as its ossuary, playground, brewery, and perhaps soon, air conditioning.
- People have been digging up limestone and gypsum from below Paris since Roman times.
- They left behind a vast network of corridors and galleries, since reused for many purposes — most famously, the Catacombs.
- Soon, the ancient labyrinth may find a new lease of life, providing a sustainable form of air conditioning.

"If you're brave enough to try, you might be able to catch a train from UnLondon to Parisn't, or No York, or Helsunki, or Lost Angeles, or Sans Francisco, or Hong Gone, or Romeless."
China Miéville's fantasy novel Un Lun Dun is set in an eerie mirror version of London. In it, he hints that other cities have similar doubles. On the list that he offhandedly rattles off, Paris stands out. Because the City of Light really does have a twisted sister. Below Paris Overground is Paris Underground, the City of Darkness.
Most people will have heard of the Catacombs of Paris: subterranean charnel houses for the bones of around six million dead Parisians. They are one of the French capital's most famous tourist attractions – and undoubtedly its grisliest.
But they constitute only a small fragment of what the locals themselves call les carrières de Paris ("the mines of Paris"), a collection of tunnels and galleries up to 300 km (185 miles) long, most of which are off-limits to the public, yet eagerly explored by so-called cataphiles.
The Grand Réseau Sud ("Great Southern Network") takes up around 200 km beneath the 5th, 6th, 14th, and 15th arrondissements (administrative districts), all south of the river Seine. Smaller networks run beneath the 12th, 13th, and 16th arrondissements. How did they get there?
Paris stone and plaster of Paris
It all starts with geology. Sediments left behind by ancient seas created large deposits of limestone in the south of the city, mostly south of the Seine; and gypsum in the north, particularly in the hills of Montmartre and Ménilmontant. Highly sought after as building materials, both have been mined since Roman times.
The limestone is also known as Lutetian limestone (Lutetia is the Latin name for ancient Paris) or simply "Paris stone." It has been used for many famous Paris landmarks, including the Louvre and the grand buildings erected during Georges-Eugène Haussmann's large-scale remodelling of the city in the mid-19th century. The stone's warm, yellowish color provides visual unity and a bright elegance to the city.
The fine-powdered gypsum of northern Paris, used for making quick-setting plaster, was so famed for its quality that "plaster of Paris" is still used as a term of distinction. However, as gypsum is very soluble in water, the underground cavities left by its extraction were extremely vulnerable to collapse.

In previous centuries, a road would occasionally open up to swallow a chariot, or even a whole house would disappear down a sinkhole. In 1778, a catastrophic subsidence in Ménilmontant killed seven. That's why the Montmartre gypsum quarries were dynamited rather than just left as they were. The remaining gypsum caves were to be filled up with concrete.
The official body governing Paris down below is the Inspection Générale des Carrières (IGC), founded in the late 1770s by King Louis XVI. The IGC was tasked with mapping and, where needed, propping up the current and ancient (and sometimes forgotten) mining corridors and galleries hiding beneath Paris.
A delightful hiding place
Also around that time, the dead of Paris were getting in the way of the living. At the end of the 18th century, their final destination consisted of about 200 small cemeteries, scattered throughout the city — all bursting at the seams, so to speak. There was no room to bury the newly dead, and the previously departed were fouling up both the water and air around their respective churchyards.
Something radical had to happen. And it did. From 1785 until 1814, the smaller cemeteries were emptied of their bones, which were transported with full funerary pomp to their final resting place in the ancient limestone quarries at Tombe-Issoire. Three large and modern cemeteries were opened to receive the remains of subsequent generations of Parisians: Montparnasse, Père-Lachaise, and Passy.
The six million dead Parisians in the Catacombs, from all corners of the capital and across many centuries, together form the world's largest necropolis — their now anonymized skulls and bones methodically stacked, occasionally into whimsical patterns. The Catacombs are fashioned into a memorial to the brevity of life. The message above the entrance reads: Arrête! C'est ici l'empire de la Mort. ("Halt! This is the empire of Death.")
That has not stopped the Catacombs, accessible via a side door to a classicist building on the Avenue du Colonel Henri Rol-Tanguy, making just about every Top 20 list of things to see in Paris.
An underground economy
However, while the Catacombs certainly are the most famous part of the centuries-old network beneath Paris, and in non-pandemic times draw thousands of tourists each day, they constitute just 1.7 km (1 mile) of the 300-km (185-mile) tunneling total.
Subterranean Paris wasn't just used for mining and storing dead people. In the 17th century, Carthusian monks converted the ancient quarries under their monastery into distilleries for the green or yellow liqueur that still carries their name, chartreuse.
Because the mines generally keep a constant cool temperature of around 15° C (60° F), they were also ideal for brewing beer, as happened on a large scale from the end of the 17th century until well into the 20th century. Several caves were dug especially for establishing breweries, and not just because of the ambient temperature: going underground allowed brewers to remain close to their customers without having to pay a premium for real estate up top.

At the end of the 19th century, the underground breweries of the 14th arrondissement alone produced more than a million hectoliters (22 million gallons) per year. One of the most famous of Paris' underground breweries, Dumesnil, stayed in operation until the late 1960s.
In that decade, the network of corridors and galleries south of the Seine, long since abandoned by miners, became the unofficial playground for the young people of Paris. They explored the fantastical world beneath their feet, in some cases via entry points located in their very schools. Fascinated, these cataphiles ("catacomb lovers") read up on old books, explored the subterranean labyrinth, and drew up schematics that were passed around among fellow initiates as reverently as treasure maps.
As Robert Macfarlane writes in Underland, Paris-beneath-their-feet became "a place where people might slip into different identities, assume new ways of being and relating, become fluid and wild in ways that are constrained on the surface."
Some larger caves turned into notorious party zones: a 7-meter-tall gallery below the Val-de-Grâce hospital is widely known as "Salle Z." Over the last few decades, various other locations in subterranean Paris have hosted jazz and rock concerts and rave parties — like no other city, Paris really has an "underground music scene."

Cataphiles vs. cataphobes
With popularity came increased reports of nuisance and crime — the tunnels provided easy access to telephone cables, which were stolen for the resale value of their copper.
The general public's "discovery" of the underground network led the city of Paris to officially interdict all access by non-authorized persons. That decree dates back to 1955, but the "underground police" have an understanding with seasoned cataphiles. Their main targets are so-called tourists, who by their lack of knowledge expose themselves to risk of injuries or worse, and degrade their surroundings, often leaving loads of litter in their wake.
The understanding does not extend to the IGC. Unlike in the 19th century, when weak cavities were shored up by purpose-built pillars, the policy now is to inject concrete to fill up endangered spaces — thus progressively blocking off parts of the network. That procedure has also been used to separate the Catacombs to prevent "infiltration" of the site by cataphiles.
Many subterranean streets have their own names, signs and all. This is the Rue des Bourguignons (Street of the Burgundians) below the Champs des Capucins (Capuchin Field), neither of which exists on the surface.Credit: Jean-François Gornet via Wikimedia and licensed under
The cataphiles, however, are fighting back. In a game of cat and mouse with the authorities, they are reopening blocked passages and creating chatières ("cat flaps") through which they can squeeze into chambers no longer accessible via other underground corridors.
Catacomb climate control
Alone against the unstoppable tide of concrete, the amateurs of Underground Paris would be helpless. But the fight against climate change may turn the subterranean labyrinths from a liability into an asset — and the City of Paris into an ally.
The UN's 2015 Climate Plan — concluded in Paris, by the way — requires the world to reduce greenhouse gas emissions by 75 percent by 2050. And Paris itself wants to be Europe's greenest city by 2030. More sustainable climate control of our living spaces would be a great help toward both targets. A lot of energy is spent heating houses in winter and cooling them in summer.
This is where the constant temperature of the Parisian tunnels comes in. It's not just good for brewing beer; it's a source of geothermal energy, says Fieldwork, an architectural firm based in Paris. It can be used to temper temperatures, helping to cool houses in summer and warming them in winter.
One catch for the cataphiles: it also works when the underground cavities are filled up with concrete. So perhaps one day, Paris Underground, fully filled up with concrete, will completely fall off the map, reducing the city's formerly real doppelgänger into an air conditioning unit.

Strange Maps #1083
Got a strange map? Let me know at email@example.com.
Meconium contains a wealth of information.
- A new study finds that the contents of an infants' first stool, known as meconium, can predict if they'll develop allergies with a high degree of accuracy.
- A metabolically diverse meconium, which indicates the initial food source for the gut microbiota, is associated with fewer allergies.
- The research hints at possible early interventions to prevent or treat allergies just after birth.
The prevalence of allergies arising in childhood has increased over the last 50 years, with 30 percent of the human population now having some kind of atopic disease such as eczema, food allergies, or asthma. The cause of this increase is still subject to debate, though it has been associated with a number of factors, including changes to the gut microbiomes of infants.
A new study by Canadian researchers published in Cell Reports Medicine may shed further light on how these allergies develop in children by examining the contents of their first diaper.
The things you do for science
The research team examined the first stool of 100 infants from the CHILD Cohort Study. The first stool of an infant is a thick, green, horrid-looking substance called meconium. It consists of various things that the infant ingests during the second half of gestation. Additionally, it provides not only a snapshot of what the infant was exposed to during that time, but it also reveals what the food sources will be for the initial gut bacteria that colonize the baby's digestive tract.
The content of the meconium was examined and found to contain such varied elements as amino acids, lipids, carbohydrates, and myriad other substances.
A graph of the comparative, summed abundance of different elements in a metabolic pathway after scaling to median abundance of each metabolite. The blue figures are those children without atopy, the yellow ones show the data for those with an atopic condition. Petersen et al.
The authors fed this information into an algorithm that used this data, along with the identities of the bacteria present as well as the baby's overall health, to predict which infants would go on to develop allergies within one year. The algorithm got it right 76 percent of the time.
A way to prevent childhood allergies?
Infants whose meconium had a less diverse metabolic niche the initial microbes to settle in the gut were at the highest risk of developing allergies a year later. Many of these elements were associated with the presence or absence of different bacterial groups in the digestive system of the child, which play an increasingly appreciated role in our overall health and development. The findings were summarized by senior co-author Dr. Brett Finlay:
"Our analysis revealed that newborns who developed allergic sensitization by one year of age had significantly less 'rich' meconium at birth, compared to those who didn't develop allergic sensitization."
The findings could be used to help understand how allergies form and even how to prevent them. Co-author Dr. Stuart Turvey commented on this possibility:
"We know that children with allergies are at the highest risk of also developing asthma. Now we have an opportunity to identify at-risk infants who could benefit from early interventions before they even begin to show signs and symptoms of allergies or asthma later in life."
A model for early childhood allergies
Petersen et al.
As shown above, the authors constructed a model of how they believe metabolites and bacterial diversity help prevent allergies. Increased diversity of metabolic products in the meconium encourage the development of "healthy" families of bacteria, like Peptostreptococcaceae, which in turn promote the development of a healthy and diverse gut microbiome. Ultimately, such diversity decreases the likelihood that a child will develop allergies.
