I'm all for an "autopilot" in a car such as in an airplane, just as long as there is a way to override the system in case of failure.

but on the same hand, with the amount of vehicles, either it has to be one hell of a smart system that in constantly monitoring other vehicles and what they are doing and making actions on that....or ALL cars need to be talking to each other and in autodrive, with the only exception being during a failure and manual control is required.
