9 ways self-driving vehicles could change tourism
Future vacationing could be pretty different.
- A study examines how autonomous vehicles could change the tourism experience
- Removing a human driver adds some new possibilities, like personalized sightseeing tours
- Sex on wheels, anyone?
While experts and manufacturers often assert that self-driving vehicles will come to market by 2020, others are skeptical, as some required elements are far from realization, among them digital maps for cars and cheap enough onboard sensors, computers, and power supplies. (Current hardware is prohibitively expensive for mass production.) Also, more robust networks will be required for all of these connect vehicles. Still, people are already considering the eventual passenger experience — what will we do as we're ferried hither and yon?
In the January 2019 issues of Annals of Tourism Research is an article by the University of Surrey's Scott A.Cohen and Oxfords' Debbie Hopkins. The article's called "Autonomous vehicles and the future of urban tourism," and it examines the impact of future autonomous vehicles on urban tourism. The researchers consider the ways in which sightseeing, recreation, and lodging may change once the technology has matured to the point that vacationers are comfortable enough to let their connected autonomous vehicles, or personal CAVs — and shared, connected autonomous vehicles, or SCAVs — do the driving. Absent the cost of human drivers and with the presumed greater safety — especially with the removal of jet-lagged travelers from behind the wheels of rental cars — Cohen and Hopkins suggest a number of things that could be different.
1. Self-driving taxis
One of the sectors benefiting most from current tourism is taxi drivers. With self-driving vehicles, however, cab drivers could be largely put out of business. On the other hand, self-driving cars are expect to be safer than human-driven cars, so passengers may prefer a less dangerous ride through a new city.
2. Targeted sightseeing
Imagine sightseeing vehicles programmed to satisfy the visitors being shown around town. A pre-trip questionnaire could result in a map optimized for the travelers' interests, reducing the potential for wasted ho-hum vacation moments.
The authors note a couple of potential downsides. First, once the sightseeing vehicle "knows" what interest you, would it also bombard you with onboard targeted ads? Also, the impact of private sightseeing CAVs — as opposed to multi-traveler SCAVs — could lead to greater urban congestion.
3. Extended sightseeing

Another possible outcome the authors suggest is that sightseeing tours could inexpensively cover larger areas, allowing for more expansively themed trips. Onboard recreations could be provided to keep visitors engaged and amused. Which brings us to…
4. Rolling hotel rooms
With tourists feeling safe in their vehicles, why not catch some sleep en route to the next destination? Ideally, it would look a more comfortable than this, but the thought is there. If people can catch sleep on planes, why not make ground travel more sleepable and appealing?
5. Rolling entertainment
Or you could catch a show. How about a movie, or some sort of VR/AR entertainment? Experiencing a VR environment — related to your real location or not — could be a really fun way to get from place to place.
6. If the SCAV’s rocking, don’t come a-knocking
The report notes the relative lack of interest in studying nyctalopia in that academia "tends to overlook what happens when night falls." Thinking about this, though, autonomous vehicles may see "a variety of practices and emotions gain traction within a particular space-time which generates a special atmosphere associated with particular activities, experiences and possibilities." Night-time travel, like any night-time venue, could provide a mobile setting for "criminal acts, a rendezvous for lovers, nonconventional behaviors, or organizing rebellion."
So, yeah, mobile sex. And maybe revolution.
7. Events and parties
Could larger CVAs contain moving events or parties that allow an organizer to control the atmosphere more absolutely without concerns of its effect on a stationary space? We're thinking easier cleanups, better security, etc. SCAVs could also gather its participants as as the night rolls on.
8. Restaurants and bars
If diners enjoy viewing a skyline from up high while eating, why not the ever-changing nighttime cityscape of well-planned urban tour passing by at ground level? The same could apply to watering holes — why just stare at a bartender when you could be taking in the sights?
9. Less parking to be done

One great way to make money for a developer is to open a parking garage in a popular tourist destination. With tourists riding around in SCAVs instead of private vehicles, though, that investment seems considerably less attractive. Of course, tourists will no longer have the difficulty or expense of finding somewhere to park. On-street and roadside parking would also be less necessary, and the authors wonder, "What if parking lots and roadside parking could be transformed into city parks, event spaces and bike lanes?"
Automated tourism of the future, or not? Discuss.
Taxis, sightseeing, and parking changes all seem inevitable and desirable. But it's fair to ask of this study exactly how much of this ambulatory activity is actually desirable, or even that new? After all, people sleep on trains as they travel already, and on planes. Would people prefer sex for some reason in a moving vehicle to a stationary room somewhere? (Mind the potholes.) Much of what's envisioned in the study is already doable with a human driver, and one wonders how much more popular such activities would become absent that one factor — we see very few people engaging in them now. We'll have to wait and see.
Scientists discovered footprints made by some of the largest creatures ever to walk the Earth.
- Paleontologists published a paper on the discovery of dinosaur footprints on the roof of a French cave.
- The prints are deep underground and were made during the Middle Jurassic period.
- The footprints belonged to titanosaurs, the largest land animals ever.
French scientists found gigantic dinosaur footprints on the roof of the Castelbouc cave the Lozère region of southern France. A new paper outlines the discovery approximately 1640 feet under ground by the paleontologist Jean-David Moreau from the University of Burgundy–Franche-Comté and his colleagues.
The footprints likely belonged to an unknown species of titanosaur and were made 166 to 168 million years ago, in the Middle Jurassic Period. Titanosaurs, a group of long-necked, lizard-like sauropods, could be found all over the world in present day Africa, the Americas, Europe, and Australia. Among titanosaurs were the largest land animals to have ever existed, like the Patagotitan, which stretched 121 feet long and weighed 138,000 pounds.

Some of the 38 tracks found in France were as large as 4 feet long. They were likely made by three dinosaurs at the time when the area was on the surface, making up a muddy shoreline along which the giant creatures traveled. Over time, the site was buried by geological processes, with the tracks becoming moldings in the roof of a cave that's half a kilometer underground.
They were spotted as part of a caving expedition in December 2015 by the paper's authors. To find them, the scientists had to go down a narrow labyrinth of crawl spaces that often get flooded. The tracks were in a space about 260 feet long, 66 feet wide and 33 feet high.

Speaking to the French science magazine Sciences et Avenir, Jean-David Moreau explained that a caver "who was ahead of me turned to me and with the lamp of his helmet projected a grazing lighting on the ceiling which allowed to bring out the marks."

Humans may have evolved to be tribalistic. Is that a bad thing?
- From politics to every day life, humans have a tendency to form social groups that are defined in part by how they differ from other groups.
- Neuroendocrinologist Robert Sapolsky, author Dan Shapiro, and others explore the ways that tribalism functions in society, and discuss how—as social creatures—humans have evolved for bias.
- But bias is not inherently bad. The key to seeing things differently, according to Beau Lotto, is to "embody the fact" that everything is grounded in assumptions, to identify those assumptions, and then to question them.
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.

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.
