The autonomous vehicle industry has been dealt a sharp reminder of its limitations, with Waymo recalling approximately 3,800 robotaxis across the United States after one of its driverless cars attempted to navigate a flooded lane during heavy rain in San Antonio, Texas. The incident, which occurred on April 20th, prompted an investigation by the National Highway Traffic Safety Administration (NHTSA) and forced Waymo, a subsidiary of Alphabet, to admit that its fifth- and sixth-generation automated driving systems could fail to detect standing water on high-speed roads. Although the vehicle was empty and no injuries were reported, the company has since updated its digital maps and imposed stricter weather operating limits, while a permanent software fix remains under development. Viewed from Washington, the recall underscores the regulatory challenge of policing a technology that promises safety but still stumbles on edge cases such as urban flooding.

Tesla, meanwhile, is confronting its own safety and strategic turbulence. The company has recalled all 173 rear-wheel-drive Cybertrucks sold over the past two years after the NHTSA warned that fragile stud holes could cause wheel stud separation, increasing crash risk. The paltry number of affected vehicles is itself a telling indicator of the Cybertruck’s sluggish sales performance since its launch. In a more symbolic move, Tesla announced the end of production for its Model S and Model X vehicles at its Fremont, California, factory, closing a chapter that transformed the company from a Silicon Valley startup into America’s dominant electric vehicle seller. The retirements leave Tesla’s lineup reduced to the Model 3, Model Y and Cybertruck, and highlight how heavily the company now bets on automation and robots rather than its original luxury sedans. On a more mundane front, Tesla is piloting a digital waitlist system at five Supercharger locations in California and New York to manage chaotic charging queues, a small operational fix that reveals the infrastructure strains accompanying EV adoption.

Beyond America’s troubles, the autonomous taxi revolution is quietly advancing into European cities. Waymo has launched a fleet of around fifty self-driving vehicles in London, while in the Croatian capital of Zagreb, the company Verne has begun operating robotaxis in partnership with China’s Pony.ai and Uber. Other firms are now exploring markets in Sweden and elsewhere. Yet these expansions have drawn a cautionary response from analysts in Europe, who warn that cities should not cede control of their streets to the monopolistic ambitions of tech giants including Alphabet, Amazon and Tesla. The Swedish business daily Dagens Industri has argued that the simple business model of replacing private cars with driverless taxis – eliminating driver costs – risks turning urban mobility into a private, data-driven fiefdom if regulators fail to impose strict public-interest conditions.

Taken together, the week’s events illustrate an industry at a crossroads. Waymo’s recall, though small in absolute scale, exposes the fragility of autonomous systems when confronted with real-world weather extremes. Tesla’s production cutbacks and its own recall suggest that even the most celebrated EV manufacturer is struggling to maintain momentum amid falling sales and rising competition. Meanwhile, the cautious but real inroads of robotaxis into Europe pose a regulatory puzzle: how to encourage innovation without repeating the mistakes that have plagued the sector in the United States. The coming months will show whether companies can refine their software fast enough to regain public trust, or whether the promise of fully driverless mobility will remain just out of reach, stalled by the same rain that floods our roads.
