Robotaxis in 2026: Where Waymo, Zoox and Tesla Actually Operate

Robotaxis are no longer only demonstrations. In some US zones, a customer can request a car that completes the ride without a human driver. But that sentence does not describe every city, every road or every system sold to consumers.

Level 2 is not Level 4

NHTSA uses a scale from 0 to 5. At Levels 0 to 2 the driver remains responsible and must supervise. Level 3 may drive under defined conditions but asks for takeover. Level 4 performs the whole driving task inside its operational domain without relying on human takeover; Level 5 would cover every road and condition a person can handle.

Commercial robotaxis are mainly Level 4 systems limited by geography, weather and operating rules. Driver assistance on a personal car is not a robotaxi.

Waymo: the largest commercial footprint

Waymo has expanded service across several metro areas. In February 2026 it announced public access in Dallas, Houston, San Antonio and Orlando, taking its commercial service to ten metro areas according to the company. It attributes millions of rides and a substantial reduction in serious crashes versus comparable human driving to its fleet.

Those statistics are useful but need their method: mileage, geography, severity definition, time period and comparison group. The regulator also warns that automated-system incident reports have limitations and do not support a raw ranking between companies.

Zoox: a vehicle designed without a driver

Zoox is developing a symmetrical vehicle without a conventional steering wheel instead of modifying a standard car. In 2026 it expanded passenger rides, including in San Francisco, still inside a defined geography and operating model. The architecture creates cabin space but requires validation of an entirely new vehicle and operating chain.

Tesla: follow the network city by city

Tesla presents Robotaxi service in several Texas cities on its official page. That service must be separated from driver-assistance features sold to owners, which can retain different supervision requirements. For each city, check who is in the driver's seat, whether an onboard monitor is present, the zone and whether public access is open.

Edge cases remain the real test

Temporary construction, traffic officers, emergency vehicles, heavy rain, dropped objects and unpredictable road users are difficult because they combine perception with social judgement. A fleet can reduce risk by avoiding a street, stopping or requesting remote assistance.

Assistance does not necessarily mean a person drives continuously. It should still be documented: frequency, latency, authorised decisions and procedure if connectivity fails.

How to compare safety

Do not simply divide crashes by distance without checking exposure. An urban fleet travels slowly but meets more intersections; human driving also includes highways and rural roads. Injuries, crash type and responsibility matter more than an isolated count.

The 2026 verdict: commercial Level 4 exists and is expanding, mainly as a geofenced service. Universal autonomy sold to every driver remains another step. For automated freight, read our autonomous-truck dossier.
