Personally, neither. I strongly believe that the only autonomous tech a general purpose, manned car should ever have is assistive and emergency systems, not replicative systems. Meaning, collision breaking, lane-keep assist, road-departure warning, adaptive cruise, blind spot monitoring, etc. You can get these on an Accord nowadays. General purpose cars are used in too many situations for general purpose autonomous systems to operate in. Moreover, the addition of autonomous systems means that the human behind the wheel will be less vigilant about keeping themselves and other drivers safe. I very strongly believe that autonomous systems beyond L2 actually do not make the car safer, except in situations where the driver is impaired; they just make the car more convenient. L4 has definite possibility for things like uber where pickup and dropoff are within the same city. But it seems increasingly unlikely that we'll see L5 within our lifetimes, at least from any ethical company who doesn't oversell what the system is capable of.
