Who runs what
Four names matter right now. One runs the largest driverless fleet, one has the most interesting regulatory precedent, one is the only service using two different vehicles, and one owns no vehicles at all.

| Operator | Where | Fleet | Vehicle | Notes |
|---|---|---|---|---|
| Waymo Alphabet | 15 US metros | Over 4,000 | Jaguar I-PACE, and Ojai minivans with the sixth-generation driver | The only company running fully driverless commercial ride-hailing at scale in the US. Imports of Ojai are reported to reach 5,100 by the end of 2026. Closed $5bn in debt financing in October 2026. Waymo, TechCrunch |
| Zoox Amazon | 2 public, 2 more with vehicles on the road | About 100 | Purpose-built robotaxi, no steering wheel, bidirectional | Holds the first Part 555 commercial exemption NHTSA has granted for a purpose-built robotaxi, which is the regulatory event worth watching here. Zoox |
| Tesla Tesla | 6 markets, Cybercab in 1 | 739 registered in Texas, of which 319 are Cybercabs | Cybercab in Austin; modified Model Y elsewhere | The only operator using two different vehicle types under one brand. Only Austin has the Cybercab, which is a distinction most coverage blurs. Texas AV Tracker |
| Uber Uber | Austin and Atlanta via Waymo | n/a | None of its own | Runs no vehicles. Its strategy is to be the booking layer for other people's fleets, which makes it a partner and a competitor at once. Waymo |
Also operating
Baidu’s Apollo Go, Pony.ai and WeRide also run public robotaxi services, largely in China, and have been expanding internationally. Their published city lists are harder to verify from primary sources in English, so they are not counted in the table above. If you can point at a primary source for any of them, it belongs here.
The distinction that matters
Two words get used interchangeably and should not be. Driverless means no human aboard. Many services described in coverage as robotaxis still carry a safety monitor, and a service you cannot book without a chaperone is a different product from one you can. Where a service is supervised, this site says so.
