What robotaxis exist now and when they're launching
Two robotaxi services have already begun operating with paying passengers in the United States: Waymo (owned by Alphabet) and Cruise (owned by General Motors). Waymo launched paid robotaxi rides in San Francisco in October 2023 and expanded to Phoenix, Arizona in 2024. Cruise operated in San Francisco until October 2024, when it paused operations following a collision involving one of its vehicles and a pedestrian.
Waymo's service in San Francisco operates 24 hours a day and covers a growing portion of the city. In Phoenix, Waymo operates during daytime and evening hours across a defined service area. Both services use a mobile app to request rides, similar to traditional ride-hailing apps, though availability depends on whether you live or work within their operating zones.
Other companies have announced plans but have not yet launched paid service to the public. Tesla has discussed a robotaxi service but has not provided a confirmed launch date. Uber and Lyft have partnerships with autonomous vehicle companies but do not operate their own fleets of driverless cars.
Key Takeaways
- Waymo currently operates paid robotaxi service in San Francisco and Phoenix, with service hours and coverage areas that vary by city.
- Cruise paused operations in San Francisco in October 2024 after a safety incident and has not announced when service will resume.
- Service is only available within specific geographic zones in each city, and you need the company's app to request a ride.
- Other companies including Tesla have announced robotaxi plans but have not yet launched paid service to passengers.
- Robotaxis operate without a human driver, but the vehicle is monitored remotely and can be controlled by a safety operator if needed.
How robotaxi service actually works when you request a ride
When you open the Waymo app in San Francisco or Phoenix, you enter your pickup and dropoff locations just as you would with a traditional ride service. The app shows you whether a robotaxi is available in your area. If one is, you confirm the ride and the vehicle arrives to pick you up.
Once you're in the vehicle, there is no human driver in the front seat. The car is controlled by its autonomous driving system, which uses cameras, radar, and lidar (a laser-based sensor) to navigate streets, detect obstacles, and follow traffic rules. A remote operations center monitors the vehicle during the ride, and a safety operator can take control if the system encounters a situation it cannot handle on its own.
The ride experience is similar to a regular taxi or ride-hailing service: you sit in the back, the vehicle takes you to your destination, and you pay through the app. Waymo's pricing in San Francisco and Phoenix is comparable to Uber or Lyft during non-surge periods, though this can change.
Geographic coverage and service hours in each city
Waymo's San Francisco service covers a large portion of the city but not all neighborhoods. The service area includes downtown, the Mission District, the Financial District, and surrounding areas, but excludes some outer neighborhoods. Service operates 24 hours a day, seven days a week.
In Phoenix, Waymo operates in a defined zone that includes parts of downtown Phoenix and surrounding areas. Service hours are more limited than San Francisco—typically daytime through evening hours—and the company has stated it plans to expand both the service area and hours over time.
Before requesting a ride, the app will tell you whether robotaxi service is available at your pickup location. If you're outside the service area, the app will not show robotaxi as an option.
What happened with Cruise and why it matters
Cruise operated a robotaxi service in San Francisco from 2023 until October 2024. In October 2024, one of Cruise's vehicles was involved in a collision with a pedestrian. Following this incident, Cruise paused all driverless operations and has not announced a timeline for resuming service.
This pause is significant because it shows that robotaxi companies face real regulatory and public scrutiny when safety incidents occur. The California Public Utilities Commission, which oversees autonomous vehicle services in the state, can suspend or revoke a company's permit to operate. Cruise's pause demonstrates that even companies with years of testing experience can face operational setbacks.
For riders in San Francisco, this means Waymo is currently the only robotaxi service operating in the city. Cruise's situation also illustrates that robotaxi timelines are not may provide—companies can lose the right to operate if regulators determine their safety record warrants it.
How robotaxis are regulated and why launch dates change
Robotaxis in California operate under permits issued by the California Public Utilities Commission. The company must demonstrate that its vehicles can operate safely in the specific conditions of the city where it wants to launch. This means a company cannot straightforward decide to launch everywhere at once—it must prove safety in each location.
Regulators can also impose conditions on permits, such as limiting service to certain hours, requiring remote monitoring, or restricting operation to specific neighborhoods. These conditions can change if the company's safety record improves or if incidents occur.
Other states have different regulatory frameworks. Arizona, where Waymo operates, has been more permissive of autonomous vehicle testing and deployment. This is why Waymo was able to expand to Phoenix relatively quickly. States that have not yet developed clear regulations for robotaxis may see delayed launches from companies waiting for legal clarity.
What companies have announced but not yet launched
Tesla has discussed plans for a robotaxi service, sometimes referred to as the "Tesla Bot Taxi" or "Cybercab," but has not launched paid service to the public. The company has not provided a confirmed launch date, though executives have mentioned timelines ranging from 2025 onward in various statements. Tesla's approach differs from Waymo and Cruise because it relies on camera-based vision rather than lidar sensors.
Uber and Lyft have partnerships with autonomous vehicle companies but do not operate their own robotaxi fleets. Uber has worked with companies like Waymo and Aurora, while Lyft has partnered with Waymo. These partnerships mean that in the future, you might request a ride through Uber or Lyft and receive a robotaxi, but the vehicle and technology are provided by the autonomous vehicle company, not by Uber or Lyft themselves.
Amazon's Zoox division has been developing autonomous vehicles but has not announced a public robotaxi service launch date. Several other startups are testing vehicles, but most are still in the testing phase and have not begun carrying paying passengers.
Why robotaxi launch dates are hard to predict
Robotaxi companies face technical, regulatory, and public acceptance challenges that can delay launches. Technical challenges include teaching the vehicle to handle edge cases—unusual situations like construction zones, broken traffic lights, or pedestrians behaving unpredictably. These scenarios require thousands of miles of testing and refinement.
Regulatory approval is not automatic. A company must submit detailed safety data, demonstrate its testing procedures, and prove that its vehicles meet state and local requirements. This process can take months or years. If a company has a safety incident, regulators may pause or revoke its permit, pushing back any planned expansion.
Public acceptance also matters. Cities and neighborhoods may resist robotaxi deployment if residents have concerns about safety or job displacement. Some cities have imposed restrictions on where robotaxis can operate or how many vehicles can be on the road at once. These local decisions can affect a company's launch timeline.
Frequently Asked Questions
Can I use Waymo if I don't live in San Francisco or Phoenix?
Not yet. Waymo currently operates only in those two cities. If you visit San Francisco or Phoenix, you can use the service within the designated coverage areas. The company has not announced which cities it will expand to next.
Is it safe to ride in a robotaxi?
Waymo's vehicles have completed millions of miles of testing and are monitored by remote operators during every ride. However, no vehicle—autonomous or human-driven—is risk-free. Robotaxis are subject to regulatory oversight, and companies must maintain safety records to keep their operating permits. Cruise's pause after a safety incident shows that regulators take incidents seriously.
Will robotaxis replace all taxi and ride-hailing drivers?
That is uncertain and depends on how widely robotaxis are deployed and how quickly. Currently, robotaxis operate in only two cities and cover limited areas within those cities. Even if robotaxis expand significantly, human drivers may continue to operate in areas where robotaxis are not available or for passengers who prefer human drivers.
How much does a robotaxi ride cost?
Waymo's pricing in San Francisco and Phoenix is generally comparable to Uber or Lyft during standard demand periods. Prices can vary based on distance, time of day, and demand. You can see the estimated fare in the app before you confirm the ride.
What if something goes wrong during a robotaxi ride?
The vehicle is monitored by a remote operations center, and a safety operator can take control if needed. If you have an emergency or safety concern, you can contact support through the app or use the vehicle's emergency button. The vehicle can also pull over and stop if the system detects a problem it cannot resolve.
