Robotaxis Explained: How Waymo, Tesla and Zoox Differ
Waymo retrofits existing cars and ran in 15 US markets as of September 2026. Tesla relies on cameras and its Cybercab. Zoox builds a vehicle with no steering wheel under a federal exemption.

Coverage of Waymo, Tesla, Zoox and Chinese robotaxi operators: where driverless rides are available, what the safety data shows and how regulators are responding.
Robotaxis are ride-hailing cars that drive with no one at the wheel. They have moved from pilot projects into regular paid service in a growing list of US cities. This section tracks where those services run and who operates them. It follows how the safety evidence holds up and how the rules are changing. It covers Waymo, Tesla, Zoox and the Chinese operators Baidu Apollo Go, Pony.ai and WeRide. It also explains the line between driver-assistance features in consumer cars and vehicles that drive themselves.
Scale is the first story. Waymo, majority-owned by Alphabet, went from three cities in September 2024 to 15 two years later. It added Las Vegas in September 2026. TechCrunch puts its fleet at roughly 4,000 robotaxis. TechCrunch reported on September 1, 2026, that Tesla was charging for driverless Model Y rides in six Texas and Florida cities. Service was limited in some, it said. Days later Tesla put its Cybercab, which has no steering wheel or pedals, on Austin streets, and federal regulators opened an investigation into how the vehicle was certified. Amazon-owned Zoox began charging for rides in Las Vegas on August 10, 2026. That came after the National Highway Traffic Safety Administration (NHTSA) granted a temporary exemption for Zoox's purpose-built vehicle.
Safety evidence is the second. Waymo's own data hub reports 82% fewer injury-causing crashes than human drivers over 271.3 million driverless miles through June 2026. But that comparison is produced by the company and depends on its methodology. NHTSA collects crash reports from operators. It cautions that the counts are not adjusted for miles driven. Articles in this section say who produced each figure and give a date for every city list.
