No car drives itself completely, but several can handle highway driving without your hands on the wheel

The cars marketed as "self-driving" fall into two groups: those that can steer, accelerate, and brake on highways without you touching the controls, and those that can only help you park or stay in your lane. Neither one drives itself in the way the phrase suggests. A Level 2 system — which is what Tesla's Autopilot, GM's Super Cruise, and Ford's BlueCruise actually are — keeps the car centered in its lane and matches the speed of traffic ahead. You still have to watch the road, stay ready to take over, and keep your hands near the wheel. A Level 3 system, which Audi and Mercedes have released in limited markets, can handle more situations without your input, but still requires you to be ready to take control within seconds if something goes wrong.

No car sold to the public in the United States right now is a Level 4 or Level 5 system — meaning no car can truly drive itself in all conditions or most conditions. Waymo operates robotaxis (driverless vans) in Phoenix, San Francisco, and Los Angeles, but you cannot buy one. Cruise, which was owned by General Motors, suspended its robotaxi service in 2024 after a collision. If you see a car advertised as "fully self-driving" or "autonomous," the company is using those words to describe a driver-information system, not a car that can operate without a driver.

Key Takeaways

  • Tesla Autopilot, GM Super Cruise, and Ford BlueCruise are Level 2 systems that can steer and control speed on highways, but you must watch the road and be ready to take over at any moment.
  • Level 2 systems work best on divided highways with clear lane markings and do not work reliably in heavy rain, snow, or construction zones.
  • You are legally responsible for the car's actions even when the system is engaged, and insurance claims may be denied if you were not paying attention.
  • No car you can buy today is truly self-driving — robotaxis exist only in a few cities and are operated by companies, not sold to consumers.

How Level 2 systems actually work on the road

A Level 2 system uses cameras, radar, and sometimes lidar (a laser-based sensor) to see the road ahead and the lane markings on either side. The system can adjust your speed to match the car in front of you, keep you centered in your lane, and even change lanes if you signal — though you have to confirm the lane change by holding the turn signal. On a straight highway with clear markings and moderate traffic, the system can handle these tasks for hours without your input.

The catch is that the system fails in situations it was not trained to handle. Heavy rain or snow can blind the cameras. Construction zones with temporary lane markings confuse the system. Faded or missing lane lines make it impossible for the system to know where the lane is. A stopped car in your lane, a pothole, or a piece of debris in the road — these are things the system may not see or may misinterpret. If the system encounters something it cannot handle, it will alert you to take over, usually with a chime and a message on the dashboard. If you do not respond within a few seconds, the car will slow down and eventually pull over.

What happens if something goes wrong while the system is driving

You are the driver, legally and financially. If the car hits another vehicle, a pedestrian, or property while the system is engaged, you are responsible for the collision. Your insurance company can deny a claim if they determine you were not paying attention or were not ready to take control. Several insurance companies now ask whether you use driver-information systems and may charge more if you do, or may require you to take a course on how to use the system safely.

The car's manufacturer is not liable for what happens while the system is driving. Tesla's terms of service explicitly state that Autopilot is a driver-information feature and that the driver is responsible for the car's actions at all times. If a Tesla on Autopilot causes a collision, Tesla does not pay for the damage — your insurance does. This is true for GM Super Cruise, Ford BlueCruise, and every other Level 2 system on the market.

Which cars have driver-information systems and what they cost

Tesla Autopilot comes standard on all new Tesla vehicles. An upgraded version called Full Self-Driving (FSD) costs between $8,000 and $12,000 depending on the model and market, or $99 to $199 per month as a subscription. FSD adds features like automatic lane changes and navigation on city streets, but it still requires you to watch the road and is not fully autonomous.

GM Super Cruise is available on Cadillac, Chevrolet, and GMC models. It costs $2,500 to $2,800 to purchase, or $25 per month as a subscription. Super Cruise requires an eye-tracking camera to confirm you are watching the road — if you look away for too long, the system alerts you and eventually disengages.

Ford BlueCruise is available on Ford and Lincoln models and costs $600 to $1,200 depending on the vehicle, or $16 per month as a subscription. BlueCruise works on divided highways and does not require eye tracking, though Ford recommends keeping your hands near the wheel.

Audi, BMW, and Mercedes offer Level 3 systems in some markets outside the United States. Audi's Traffic Jam information, available on the A8 sedan in Europe, can drive itself in stop-and-go traffic on highways. Mercedes Drive Pilot, available on the S-Class and EQS in Germany and Nevada, can handle highway driving at speeds up to 40 mph. These systems are not yet widely available in the U.S. market.

What Level 2 systems cannot do

A Level 2 system cannot drive on city streets with traffic lights, stop signs, and pedestrians. It cannot navigate parking lots or driveways. It cannot handle merging onto a highway or exiting a highway in heavy traffic. It cannot drive in reverse or parallel park (though some cars have separate parking-information features). It cannot drive at night in areas without street lights. It cannot make decisions about which route to take or where to stop for gas or food.

The system is designed for one specific task: keeping a car centered in a highway lane and matching the speed of traffic. It does this task well on ideal roads in good weather. Outside those conditions, it becomes unreliable, and you have to be ready to take over when ready.

The difference between Level 2 and Level 3 systems

A Level 3 system can handle more situations without your input and can take responsibility for some decisions. If a Level 3 system causes a collision while it is engaged, the manufacturer may be liable rather than you — though this is still being tested in courts. Level 3 systems can drive in more weather conditions and can handle more complex road situations, but they still require you to be ready to take over within seconds.

Audi Traffic Jam information and Mercedes Drive Pilot are Level 3 systems. They can drive in stop-and-go highway traffic without you touching the controls, and they can handle some situations that Level 2 systems cannot. However, they are not available in most of the United States, and they are expensive — often $5,000 to $10,000 as an add-on to an already expensive car.

Why robotaxis are not the same as self-driving cars you can buy

Waymo and Cruise operate robotaxis — vans with no steering wheel and no pedals that drive themselves in specific cities. These are Level 4 systems, meaning they can drive themselves in most situations within a defined area. However, you cannot buy a Waymo or Cruise vehicle. You can only ride in one as a passenger, similar to calling a taxi or an Uber. Waymo operates in Phoenix, San Francisco, and Los Angeles. Cruise suspended its service in 2024 after a collision in San Francisco.

Robotaxis are not consumer products. They are operated by companies that employ engineers, safety drivers, and support staff. The company is responsible for the vehicle's actions, not the passenger. If you want a self-driving car you can own and drive whenever you want, that product does not exist yet in the United States.

Frequently Asked Questions

Can I take my hands off the wheel while using Autopilot or Super Cruise?

Technically, yes — the system is designed to work without your hands on the wheel. However, you must keep your hands near the wheel and be ready to take over within seconds. Super Cruise requires eye tracking to confirm you are watching the road. If you remove your hands and do not respond to alerts, the system will disengage and the car will slow down.

Will my insurance go up if I use a driver-information system?

Some insurance companies charge more for cars with driver-information systems, and some offer discounts if you complete a safety course. Ask your insurance company directly whether they charge more or less for the specific system in your car. If you cause a collision while using the system, your claim may be denied if the company determines you were not paying attention.

Is a self-driving car safer than a regular car?

Level 2 systems reduce driver fatigue on long highway drives and can prevent some collisions by reacting faster than a human driver. However, they can also cause collisions by misinterpreting road conditions or failing to see obstacles. The safety benefit depends on how you use the system and how much you trust it. Treating it as a convenience rather than a safety feature is the safest approach.

When will truly self-driving cars be available to buy?

No timeline is certain. Level 4 and Level 5 systems are still being tested and refined. Waymo and Cruise have been operating robotaxis for years but have not released consumer vehicles. Most manufacturers estimate that truly autonomous vehicles will not be widely available for at least five to ten years, though some timelines have been pushed back repeatedly.

What is the difference between Autopilot and Full Self-Driving?

Autopilot is a Level 2 system that comes standard on Tesla vehicles and handles highway driving. Full Self-Driving is an upgraded version that adds features like automatic lane changes, navigation on city streets, and parking information. However, Full Self-Driving is still a Level 2 system — it still requires you to watch the road and be ready to take over at any time.
