According to True Car Adviser, the five levels of car autonomy are: Level 0: No Automation. This level applies to most standard cars. At most, a vehicle at this level will have automatic cruise control. Level 1: Driver assistance. This level uses adaptive cruise control that uses radars and cameras to help ensure your car stays a safe distance from the car in front of you. The car automatically applies the brakes when traffic slows. Level 1 also uses lane assist technology to prevent your car from drifting into other lanes – when you are tired or not paying attention. Most new cars have level 1 autonomy. Level 2: Partial Automation. At this level, the driver has his/her hands on the steering wheel so he/she can take control if needed. Level 2 automation helps with steering and controlling the speed of the vehicle. Some examples of level 2 autonomy include the Tesla Autopilot, Volvo Pilot Assist, and Audi Traffic Jam Assist. Level 3: Conditional Automation. At this level, the car can drive itself – but only in ideal conditions and with some limitations such as “limited-access divided highways at a certain speed.” Drivers must be behind the steering column – though their hands are off the wheel. When conditions become non-ideal, the driver should take control of the vehicle. Level 4: High Automation. Here, the vehicle can drive itself without human input, but the operation is restricted to “known use cases.” Waymo is testing Level 4 vehicles, subject to current regulations and legal issues. Level 5: Full Automation. At this level, the car is truly without a driver. Level 5 autonomous vehicles must be able to navigate through all traffic conditions. With a level 5 vehicle, there is no need for a steering wheel or pedals. This is the type of vehicle you always see in sci-fi movies.
