Can AI drive a car without a human?
YesYes, within mapped service areas. Robotaxis carry paying passengers with nobody at the wheel, but consumer systems such as Tesla's Full Self-Driving still require an attentive driver.
First shown: Oct 8, 2020. Waymo opened its fully driverless ride-hailing service, with no safety driver, to members of the public in metro Phoenix. (Waymo)
What it means
A driverless car uses cameras, radar, lidar and AI software to see the road and decide how to drive. Robotaxi companies limit them to areas they have mapped and tested, and remote staff can help when a car gets stuck.
Waymo opened fully driverless rides to the public in Phoenix in October 2020. By May 2025 it had given 10 million paid rides, and by March 2026 about 500,000 a week across 10 US cities. Its own analysis of more than 270 million driverless miles through June 2026 found 82% fewer injury-causing crashes and 95% fewer serious-injury-or-worse crashes than human drivers in the same cities. That comparison is Waymo's, though it counts crashes regardless of fault.
Failures still happen. A Cruise robotaxi dragged a pedestrian in San Francisco in 2023 and California suspended its permits; Waymo recalled software after its cars illegally passed stopped school buses in Austin (2025) and drove into freeway work zones (2026), and one struck a child near a school in January 2026.
Cars sold to the public are different. Tesla's Full Self-Driving is a driver-assistance system that requires a supervising driver. On Oct 22, 2026, California Highway Patrol said a Tesla in Full Self-Driving mode struck and killed a 71-year-old man crossing an unlit Vallejo freeway at night; whether the system could have avoided him is not established.
The evidence ladder
Every capability on this site is graded on the same five steps, from a single demonstration to real-world consequences.
| Step | Status | When | Evidence |
|---|---|---|---|
| Demonstrated shown at least once | yes | Oct 8, 2020 | Waymo opened fully driverless rides to Waymo One members of the public in metro Phoenix. (Waymo) |
| Reproduced independently repeated | partly | Jul 8, 2026 | Tesla's Austin robotaxi ran roughly 20 driverless vehicles by mid-2026 per third-party tracking; Cruise's driverless service ended after its 2023 pedestrian-dragging incident. (Electrek) |
| Accessible available to ordinary people, or criminals | yes | Jul 8, 2026 | Waymo serves the public by app in 11 US cities (Las Vegas added July 2026), with about 500,000 paid rides a week by March 2026. (Electrek) |
| Reliable works most of the time for a defined task | yes | Sep 24, 2026 | Waymo's analysis of 270 million-plus driverless miles through June 2026: 82% fewer injury-causing crashes and 95% fewer serious-injury-or-worse crashes than human benchmarks, regardless of fault. (Waymo safety data) |
| Consequences real-world use or harm documented | yes | Jun 15, 2026 | Recalls after robotaxis passed stopped school buses (Dec 2025) and drove into freeway work zones (June 2026); a Waymo struck a child near a school (Jan 2026); Cruise lost its California permits in 2023. (CBS News) |

What it means for you
In a handful of US cities you can already ride in a car with nobody driving, and the data so far suggest fewer injury crashes than human drivers. But a car you buy with 'self-driving' features still needs you watching the road.
What to do
- Know which kind of car you're inA robotaxi with an empty driver's seat is designed to drive itself in its area; Tesla FSD and similar systems require you to supervise at all times.
- Stay alert with driver assistanceKeep hands ready and eyes on the road; the system can miss pedestrians, stopped vehicles and road works.
- Report robotaxi problemsUse the in-app reporting tool or contact the operator, and report safety issues to NHTSA.
Questions people ask
Are driverless cars safer than human drivers?
Waymo's own data on 270 million-plus miles show 82% fewer injury-causing crashes than human benchmarks in the same cities; independent long-term data are still limited.
Is Tesla Full Self-Driving actually driverless?
No. It is a driver-assistance system that requires an attentive driver, and fatal crashes have occurred with it engaged.
Where can I ride in a robotaxi?
Waymo served 11 US cities by mid-2026, including Phoenix, San Francisco, Los Angeles, Austin, Atlanta and Las Vegas.
When did fully driverless rides start?
Waymo opened fully driverless rides to the public in metro Phoenix on Oct 8, 2020.
