I refer to those smart cars that can distinguish traffic light, avoid walkers or some other work demands intelligence. For these two phase "automatic drive" and "autopilot drive", which is more accurate? and why?

An automatic drive is often used for a car where only the transmission is automatic, i.e. you don't need to manually shift gears.
The phrase autopilot drive makes it more clear that the car is doing (part of) the driving itself, though if it does not need any input from the human driver at all (apart from specifying the destination), it's often called an autonomous car.
