What Tesla's Robotaxi is and how it works

Tesla's Robotaxi is a modified Tesla vehicle—currently based on the Model 3—equipped with cameras, radar, and onboard computers that let it drive without a human at the wheel. The system, called Full Self-Driving (FSD) Supervised, processes video from eight cameras around the car and makes steering, acceleration, and braking decisions in real time. A passenger sits in the driver's seat but does not touch the controls; the car handles the route from pickup to dropoff.

Tesla began limited testing of the Robotaxi service in San Francisco and Los Angeles in late 2024, initially available only to Tesla owners and employees who had been testing FSD. The service works through the Tesla app: you request a ride, the app shows you an available Robotaxi, and the car arrives and drives you to your destination. You pay per mile, similar to Uber or Lyft pricing in those cities.

The core difference from human-driven rideshare is that there is no driver to tip, no conversation, and no backup person if something goes wrong. The car relies entirely on its onboard systems to navigate traffic, read traffic lights, avoid obstacles, and reach the destination. Tesla's software makes millions of decisions per trip based on what the cameras see.

Key Takeaways

  • Tesla's Robotaxi uses eight cameras and onboard computers to drive without a human operator, and passengers control the ride through the Tesla app.
  • The service launched in limited form in San Francisco and Los Angeles in late 2024, initially only for Tesla owners and employees already testing Full Self-Driving.
  • There is no driver present, which means no tipping, no human backup if the car malfunctions, and full reliance on the vehicle's software to handle all driving tasks.
  • The car still operates under California's autonomous vehicle testing rules, which require human monitoring and define what the vehicle can and cannot do on public roads.
  • Robotaxi rides are priced per mile through the Tesla app, and the service does not yet operate in most U.S. cities or states.

How the car sees and decides what to do

The Robotaxi's eight cameras—mounted on the front, sides, rear, and interior—create a 360-degree view around the vehicle. These cameras feed video continuously to Tesla's onboard computer, which runs neural network software trained on millions of miles of real driving data. The software identifies other cars, pedestrians, cyclists, lane markings, traffic lights, stop signs, and obstacles, then predicts what each will do next.

Based on those predictions, the software decides how to steer, when to accelerate or brake, and which route to take. The system does not rely on pre-mapped routes or GPS alone; it processes the live camera feed to navigate. This means the car can handle roads it has never driven before, as long as the software has learned patterns similar enough to recognize what it sees.

The car also has radar, which detects objects even in rain, fog, or darkness when cameras alone might struggle. However, the system is not perfect. It can misidentify objects, miss obstacles in certain lighting conditions, or make steering choices that feel abrupt or unsafe to passengers. Tesla publishes safety data showing that FSD-equipped cars have fewer accidents per mile than human drivers on average, but this data comes from Tesla's own fleet and does not account for selection bias—Tesla owners who test FSD may drive more carefully or in less challenging conditions than the general population.

What California's rules allow and require

Tesla's Robotaxi operates under California's Autonomous Vehicle Testing Permit, issued by the California Department of Motor Vehicles. This permit allows the company to test autonomous vehicles on public roads with certain restrictions. The vehicle must display a red license plate that identifies it as autonomous, and it must operate only in approved areas—currently San Francisco and parts of Los Angeles.

California's rules require that the vehicle be able to safely pull over and stop if something goes wrong. The car must also be insured, and Tesla must report any accidents or safety incidents to the state. However, the permit does not require a human safety driver to sit in the car ready to take over; Tesla's system is designed to operate fully autonomously within its approved zones.

The rules also define what the vehicle cannot do: it cannot operate on highways, in heavy rain or snow, at night in certain conditions, or in areas the state has not approved. If the car encounters a situation it cannot handle—a road closure, construction, or severe weather—it is supposed to slow down, alert the passenger, and either find an alternate route or pull over safely. In practice, passengers have reported the car stopping unexpectedly or asking them to take manual control, which defeats the purpose of a driverless ride.

Safety, liability, and what happens if something goes wrong

If the Robotaxi is in an accident, liability is unclear. Tesla's insurance covers the vehicle itself, but if a passenger is injured, it is not yet settled whether Tesla, the passenger's own insurance, or the vehicle's insurance pays for medical bills. This is a major open question in autonomous vehicle law, and different states may handle it differently as more robotaxis launch.

If the car malfunctions while driving—for example, if the software misreads a traffic light or fails to detect a pedestrian—there is no human driver to correct the mistake. The passenger cannot take over when ready the way they could in a car with manual controls. Some Robotaxis have a steering wheel and pedals that passengers can use in an emergency, but using them requires the passenger to be alert and ready, which is not realistic for someone who expected a fully autonomous ride.

Tesla has not published detailed data on how often the Robotaxi encounters situations it cannot handle or how often it makes safety-critical errors. The company reports aggregate safety metrics, but independent testing and long-term accident data do not yet exist. Passengers are essentially testing a system that is still in development, even though it is available to the public.

Where Robotaxi operates now and where it might expand

As of early 2025, Tesla's Robotaxi service is available only in San Francisco and Los Angeles, and only to Tesla owners and employees who have been testing Full Self-Driving. The company has not announced a timeline for expanding to other cities or opening the service to non-Tesla owners. Other autonomous vehicle companies—Waymo, Cruise, and others—operate robotaxis in different cities with different rules and technology, so the availability and rules vary by location.

Expansion depends on several factors: whether Tesla can improve the software to handle more complex driving scenarios, whether California and other states grant broader operating permits, and whether the company can build enough vehicles to meet demand. Tesla has said it plans to build a dedicated Robotaxi vehicle called the Cybercab, but production timelines have shifted repeatedly.

If you live outside San Francisco or Los Angeles, or if you do not own a Tesla, the Robotaxi is not an option for you right now. Waymo operates robotaxis in Phoenix, San Francisco, and Los Angeles; Cruise operates in San Francisco. Each service has different coverage areas, pricing, and vehicle types, so your options depend on where you live.

Cost and how it compares to human-driven rideshare

Tesla prices Robotaxi rides per mile, with rates that vary by location and time of day. In San Francisco and Los Angeles, the per-mile cost is roughly comparable to Uber or Lyft during normal hours, though exact pricing changes. Because there is no driver, you do not tip, which can make the total cost lower than a human-driven ride of the same distance.

However, the Robotaxi is slower than human drivers in some situations. Passengers have reported that the car drives cautiously, stops frequently, and sometimes takes longer routes than a human would choose. This means a Robotaxi ride might cost less per mile but take longer, offsetting some of the savings. If you are in a hurry, a human-driven rideshare might be faster despite the higher per-mile rate and tip.

The long-term cost advantage of robotaxis depends on whether Tesla can reduce the price of the vehicles and the software, and whether insurance and liability costs stay low. Right now, the service is priced to compete with existing rideshare, not to undercut it dramatically.

What passengers should know before requesting a Robotaxi

If you have access to Tesla's Robotaxi, understand that you are riding in a vehicle controlled entirely by software. The car will not respond to your voice commands the way a human driver would, and it cannot make judgment calls based on context or conversation. If you need to change your destination, you must do so through the app before the ride starts; changing it mid-ride is not straightforward.

The ride may be uncomfortable or feel unsafe at times. The car might brake suddenly, accelerate jerkily, or make turns that feel too sharp. Some passengers have reported that the car stops in the middle of intersections or behaves unpredictably in heavy traffic. If you feel unsafe, you can take manual control using the steering wheel and pedals, but this requires you to be alert and ready to drive.

You should also know that the service is still in testing, even though it is open to the public. Tesla is collecting data on how the system performs in real-world conditions, and problems you encounter are part of that testing process. If something goes wrong, report it through the app, but do not expect when ready resolution.

Frequently Asked Questions

Is the Robotaxi safer than a human driver?

Tesla reports that FSD-equipped vehicles have fewer accidents per mile than human drivers, but this data comes from Tesla's own fleet and may not reflect real-world conditions for robotaxis. Independent testing and long-term accident data do not yet exist. The system is good at some tasks—steady highway driving, following lane markings—but can struggle with complex urban scenarios, construction, or unusual situations.

What happens if the car breaks down or gets stuck?

If the Robotaxi encounters a situation it cannot handle, it is supposed to slow down, alert you, and either find an alternate route or pull over. In practice, passengers have reported the car stopping unexpectedly and asking them to take manual control. If you cannot drive the car yourself, you would need to call Tesla support or request a different ride.

Can I use Robotaxi if I do not own a Tesla?

Not yet. The service is currently available only to Tesla owners and employees in San Francisco and Los Angeles. Tesla has not announced when it will open the service to non-Tesla owners or expand to other cities. Other companies like Waymo operate robotaxis in some cities and do not require you to own their vehicle.

What if I get in an accident in a Robotaxi?

Liability in a robotaxi accident is not yet clearly defined by law. Tesla's insurance covers the vehicle, but whether a passenger's medical bills are covered by Tesla's insurance, the passenger's own insurance, or another source depends on the circumstances and the state. This is an evolving area of law.

Is the Robotaxi cheaper than Uber or Lyft?

The per-mile cost is roughly comparable, but you do not tip a Robotaxi, which can lower the total cost. However, the car often drives more slowly and takes longer routes than a human driver would, so the time cost may be higher. Whether it is cheaper overall depends on the specific trip and how you value your time.
