The European urban landscape has undergone a historic shift this week. With the arrival of robotaxis in Zagreb and the start of Waymo's trials in London, autonomous driving has moved from a futuristic promise to a daily reality on the continent's roads. On Wednesday, 8 April, Zagreb officially became the first city in Europe to offer a commercial robotaxi service. The project is the result of a strategic partnership between Verne (a company from the Croatian Rimac group), Pony.ai, and Uber. The service already allows the public to book trips via an app, initially covering a 90-square-kilometre area, including the capital's airport. With promotional launch fares of 1.99 euros, the vehicles—which currently still have a safety operator on board—aim to demonstrate that full autonomy is the solution to congestion and road safety. Meanwhile, on British soil, Waymo (a subsidiary of Alphabet, the owner of Google) began its pilot tests this month. London will serve as the stage for the tech company's largest expansion outside the United States. Using the Jaguar I-PACE equipped with LiDAR sensors and state-of-the-art radar, Waymo plans a full commercial launch for September 2026. The challenge is significant: navigating the narrow streets and unpredictable traffic of the London City. If successful, Waymo hopes to transform mobility in the British capital, offering a predictable and safe alternative to traditional services like Uber. Safety is the central argument: machines do not suffer from fatigue or distraction. However, the debate over privacy and data collection in autonomous cabins continues to divide opinion, promising to be the next major regulatory topic in Europe.
