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%.
All this from a wad of gum?
- Researchers recently uncovered a piece of chewed-on birch pitch in an archaeological dig in Denmark.
- Conducting a genetic analysis of the material left in the birch pitch offered a plethora of insights into the individual who last chewed it.
- The gum-chewer has been dubbed Lola. She lived 5,700 years ago; and she had dark skin, dark hair, and blue eyes.
Five thousand and seven hundred years ago, "Lola" — a blue-eyed woman with dark skin and hair — was chewing on a piece of pitch derived from heating birch bark. Then, this women spit her chewing gum out into the mud on an island in Denmark that we call Syltholm today, where it was unearthed by archaeologists thousands of years later. A genetic analysis of the chewing gum has provided us with a wealth of information on this nearly six-thousand-year-old Violet Beauregarde.
This represents the first time that the human genome has been extracted from material such as this. "It is amazing to have gotten a complete ancient human genome from anything other than bone," said lead researcher Hannes Schroeder in a statement.
"What is more," he added, "we also retrieved DNA from oral microbes and several important human pathogens, which makes this a very valuable source of ancient DNA, especially for time periods where we have no human remains."
In the pitch, researchers identified the DNA of the Epstein-Barr virus, which infects about 90 percent of adults. They also found DNA belonging to hazelnuts and mallards, which were likely the most recent meal that Lola had eaten before spitting out her chewing gum.
Insights into ancient peoples
The birch pitch was found on the island of Lolland (the inspiration for Lola's name) at a site called Syltholm. "Syltholm is completely unique," said Theis Jensen, who worked on the study for his PhD. "Almost everything is sealed in mud, which means that the preservation of organic remains is absolutely phenomenal.
"It is the biggest Stone Age site in Denmark and the archaeological finds suggest that the people who occupied the site were heavily exploiting wild resources well into the Neolithic, which is the period when farming and domesticated animals were first introduced into southern Scandinavia."
Since Lola's genome doesn't show any of the markers associated with the agricultural populations that had begun to appear in this region around her time, she provides evidence for a growing idea that hunter-gatherers persisted alongside agricultural communities in northern Europe longer than previously thought.
Her genome supports additional theories on northern European peoples. For example, her dark skin bolsters the idea that northern populations only recently acquired their light-skinned adaptation to the low sunlight in the winter months. She was also lactose intolerant, which researchers believe was the norm for most humans prior to the agricultural revolution. Most mammals lose their tolerance for lactose once they've weaned off of their mother's milk, but once humans began keeping cows, goats, and other dairy animals, their tolerance for lactose persisted into adulthood. As a descendent of hunter-gatherers, Lola wouldn't have needed this adaptation.
A hardworking piece of gum

These findings are encouraging for researchers focusing on ancient peoples from this part of the world. Before this study, ancient genomes were really only ever recovered from human remains, but now, scientists have another tool in their kit. Birch pitch is commonly found in archaeological sites, often with tooth imprints.
Ancient peoples used and chewed on birch pitch for a variety of reasons. It was commonly heated up to make it pliable, enabling it to be molded as an adhesive or hafting agent before it settled. Chewing the pitch may have kept it pliable as it cooled down. It also contains a natural antiseptic, and so chewing birch pitch may have been a folk medicine for dental issues. And, considering that we chew gum today for no other reason than to pass the time, it may be that ancient peoples chewed pitch for fun.
Whatever their reasons, chewed and discarded pieces of birch pitch offer us the mind-boggling option of learning what someone several thousands of years ago ate for lunch, or what the color of their hair was, their health, where their ancestors came from, and more. It's an unlikely treasure trove of information to be found in a mere piece of gum.
The non-contact technique could someday be used to lift much heavier objects — maybe even humans.
- Since the 1980s, researchers have been using sound waves to move matter through a technique called acoustic trapping.
- Acoustic trapping devices move bits of matter by emitting strategically designed sound waves, which interact in such a way that the matter becomes "trapped" in areas of particular velocity and pressure.
- Acoustic and optical trapping devices are already used in various fields, including medicine, nanotechnology, and biological research.
Sound can have powerful effects on matter. After all, sound strikes our world in waves — vibrations of air molecules that bounce off of, get absorbed by, or pass through matter around us. Sound waves from a trained opera singer can shatter a wine glass. From a jet, they can collapse a stone wall. But sound can also be harnessed for delicate interactions with matter.
Since the 1980s, researchers have been using sound to move matter through a phenomenon called acoustic trapping. The method is based on the fact that sound waves produce an acoustic radiation force.
"When an acoustic wave interacts with a particle, it exerts both an oscillatory force and a much smaller steady-state 'radiation' force," wrote the American Physical Society. "This latter force is the one used for trapping and manipulation. Radiation forces are generated by the scattering of a traveling sound wave, or by energy gradients within the sound field."
When tiny particles encounter this radiation, they tend to be drawn toward regions of certain pressure and velocity within the sound field. Researchers can exploit this tendency by engineering sound waves that "trap" — or suspend — tiny particles in the air. Devices that do this are often called "acoustic tweezers."
Building a better tweezer
A study recently published in the Japanese Journal of Applied Physics describes how researchers created a new type of acoustic tweezer that was able to lift a small polystyrene ball into the air.
Tweezers of Sound: Acoustic Manipulation off a Reflective Surface youtu.be
It is not the first example of a successful "acoustic tweezer" device, but the new method is likely the first to overcome a common problem in acoustic trapping: sound waves bouncing off reflective surfaces, which disrupts acoustic traps.
To minimize the problems of reflectivity, the team behind the recent study configured ultrasonic transducers such that the sound waves that they produce overlap in a strategic way that is able to lift a small bit of polystyrene from a reflective surface. By changing how the transducers emit sound waves, the team can move the acoustic trap through space, which moves the bit of matter.
Move, but don't touch
So far, the device is only able to move millimeter-sized pieces of matter with varying degrees of success. "When we move a particle, it sometimes scatters away," the team noted. Still, improved acoustic trapping and other no-contact lifting technologies — like optical tweezers, commonly used in medicine — could prove useful in many future applications, including cell separation, nanotechnologies, and biological research.
Could future acoustic-trapping devices lift large and heavy objects, maybe even humans? It seems possible. In 2018, researchers from the University of Bristol managed to acoustically trap particles whose diameters were larger than the sound wavelength, which was a breakthrough because it surpassed "the classical Rayleigh scattering limit that has previously restricted stable acoustic particle trapping," the researchers wrote in their study.
In other words, the technique — which involved suspending matter in tornado-like acoustic traps — showed that it is possible to scale up acoustic trapping.
"Acoustic tractor beams have huge potential in many applications," Bruce Drinkwater, co-author of the 2018 study, said in a statement. "I'm particularly excited by the idea of contactless production lines where delicate objects are assembled without touching them."
Australian parrots have worked out how to open trash bins, and the trick is spreading across Sydney.
- If sharing learned knowledge is a form of culture, Australian cockatoos are one cultured bunch of birds.
- A cockatoo trick for opening trash bins to get at food has been spreading rapidly through Sydney's neighborhoods.
- But not all cockatoos open the bins; some just stay close to those that do.
Dumpster-diving trash parrots
In a study about these smart birds just published in Science, researchers define animal culture as "population-specific behaviors acquired via social learning from knowledgeable individuals."
Co-lead author of the study Barbara Klump of the Max Planck Institute of Animal Behavior in Konstanz, Germany says, "[C]ompared to humans, there are few known examples of animals learning from each other. Demonstrating that food scavenging behavior is not due to genetics is a challenge."
An opportunity presented itself in a video that co-author Richard Major of the Australian Museum shared with Klump and the other co-authors. In the video, a sulphur-crested cockatoo used its beak to pull up the handle of a closed garbage bin — using its foot as a wedge — and then walked back the lid sufficiently to flip it open, exposing the bin's edible contents.
Major has been studying Cacatua galerita for 20 years and says, "Like many Australian birds, sulphur-crested cockatoos are loud and aggressive." The study describes them as a "large-brained, long-lived, and highly social parrot." Says Major, "They are also incredibly smart, persistent, and have adapted brilliantly to living with humans."(Research regarding some of the ways in which wild animals adapt to the presence of humans has already produced some fascinating results and is ongoing.)

The researchers became curious about how widespread this behavior might be and saw a research opportunity. After all, says John Martin, a researcher at Taronga Conservation Society, "Australian garbage bins have a uniform design across the country, and sulphur-crested cockatoos are common across the entire east coast."
Martin continues, "In 2018, we launched an online survey in various areas across Sydney and Australia with questions such as, 'What area are you from, have you seen this behavior before, and if so, when?'"

Although the cockatoos' maneuver was reported in only three suburbs before 2018, by the end of 2019, people in 44 areas reported observing the behavior. Clearly, more and more cockatoos were learning how to successfully dumpster dive.
As further proof, says Klump, "We observed that the birds do not open the garbage bins in the same way, but rather used different opening techniques in different suburbs, suggesting that the behavior is learned by observing others." One individual bird in north Sydney invented its own method, and the scientists saw it grow in popularity throughout the local population.
To track individual birds, the researchers marked 500 cockatoos with small red dots. Subsequent observations revealed that not all cockatoos are bin-openers. Only about 10 percent of them are, and they are mostly males. The other cockatoos apparently restrict their education to a different lesson: hang around with a bin-opener, and you will get supper.
Thanks to the surveys, the researchers consider the entire project to be a valuable citizen-science experiment. "By studying this behavior with the help of local residents, we are uncovering the unique and complex cultures of their neighborhood birds."
