Long dismissed as dangerous, hitchhiking is being rediscovered by a new generation of travellers seeking connection, adventure and a low-carbon way to see the world.

In 2022, travellers Alexandra Menz and Bernhard Endlicher were standing on the side of the road under the blazing sun near the Turkish-Syrian border, trying to make it to Mardin. It was too hot to walk, so they mustered their friendliest smiles and stuck their thumbs out to hitchhike. A car soon screeched to a halt, and inside was a bride wearing a white dress and a groom in a tuxedo.

"Hop in! We're going to our wedding," the couple said. An hour later, Menz and Endlicher found themselves in the Kurdish city of Nusaybin as guests at the couple's nuptials.

Welcome to a day in the itinerant lives of Menz and Endlicher, an Austrian duo who have documented their 4,000 car rides with strangers in more than 65 countries on social media. Lured by its low carbon footprint and high chance at authentic human connection, the couple have chosen hitchhiking as their literal and figurative vehicle to travel.

"Hitchhiking is not a thing of the past; it's a thing for the future," Menz tells the BBC.

Still, the two 25-year-olds realise that not everyone shares this sentiment. While hitchhiking was once commonplace around the world, it was later stigmatised as unsafe in the US and parts of Europe. And while it's a cheap way to travel, it's also a freedom few can afford.

For many people around the world in remote, rural areas, hitchhiking isn't a choice; it's a lifeline – the only way to reach work, school or the next town where buses are scarce. But for young travellers like Menz, Endlicher and a new generation of adventure-seekers who have time, safety nets and passports that open borders, hitchhiking offers a budget‑friendly, eco-conscious way to move through the world, meeting strangers along the way.

Hitchhiking's roots stretch back to the early 20th Century. By the 1930s, hitchhiking in the US wasn't just mainstream, but necessary, as high unemployment during the Great Depression forced many Americans to hitch rides and travel long distances in cars or freight trains in search of scarcely available jobs. When World War Two began, hitchhiking became a patriotic duty to conserve resources for the war effort, as seen in an antique US poster stating: "If you ride alone, you ride with Hitler."

But by the 1950s, fear took hold. The FBI branded hitchhiking a "menace", with director J. Edgar Hoover framing it as a safety and national security risk, as he believed that undercover agents could use it to slip through the country undetected. According to Jack Reid, author of the book Roadside Americans, which traces the practice's history in the US, Hoover instilled a campaign of fear in the US consciousness that largely still remains. A few decades later, coverage of high-profile crimes from US serial killer Edmund Kemper and Australian "backpacker killer" Ivan Milat – both of whom selected victims by offering rides to hitchhikers – cemented its dangerous reputation.

Elsewhere, the culture endured. Communist Poland and the USSR offered drivers vouchers to pick up hitchhikers; while in Cuba, "hacer botella" (hitchhiking) became essential during 1990s fuel shortages. And Ireland's friendly countryside was immortalised in Tony Hawks' best-selling travel memoir Round Ireland with a Fridge.

By the 2000s, rising car ownership and developed highway systems had pushed hitchhiking to the fringes – or so it seemed.
