All Teslas include standard autopilot, which means they can maintain speed and safe following distance and stay centered in the lane.
Related safety features are blind spot detection, lane departure warning, and emergency braking, which are also standard.
Autopilot statistically reduces accidents.
Even though it is safer than a human overall, it can make mistakes that a human might not.
You still need to pay attention and take over sometimes, but it does make driving easier.
To do all this it uses forward radar, eight cameras, twelve ultrasonic sensors, and a computer.
This hardware is standard and also supports full self-driving if you buy that.
Full Self-driving
The full self-driving option costs $6,000 and includes a growing list of advanced features but not actual self-driving yet.
Navigate on Autopilot steers the car through merging and highway interchanges.
Summon retrieves your car from a parking space without you in it.
Autopark parks your car in parallel or perpendicular spaces.
