Autonomous Cars
Autonomous cars are not ready for the public at this point. They are purely engineering test beds. What many automakers are doing is incorporating bits they believe will help improve safety such as automatically braking under certain situations. A couple of reasons for this: autopilot systems are still too buggy for the public and public is not quite ready for them. Pretty much everyone who is working on an autonomous car has said that the technology is not ready but we are "close". It may be like nuclear fusion which is always "a few years" in the future for 50 years+.
One of the problems with an autonomous vehicle is that vehicles can have a useful life of 15 years+ with proper maintenance, a little luck, and moderate use. Owners will expect similar results with an autonomous car. Many advertise that many owners get this kind of life so expectation is there. So the computer systems must work for the entire mechanical life of the vehicle which often will be 20 years.
Too name a driver assist package "Autopilot" is marketing stupidity at best if not risking a regulatory investigation for false claims.
