Funnily enough I've recently been watching some YT clips of a guy that tests how good the system is in every day driving situations. It's often found to be lacking. e.g. the car decided it was safe to pull out to overtake a slower vehicle. It didn't however pick up the presence of an oncoming vehicle. Obviously the YT guy corrected the manoeuvre. Even with basic things e.g. pulling out at a junction, it often fails to pick up on things that could lead to a collision. It also regularly failed to adhere to speed limits.
It's all very well to say humans make these mistakes daily, however surely the whole point of an automatic vehicle is to take most of the driving task away from the driver. If you still need to remain fully alert with your hands hovering over the steering wheel, what's the point?
I'm sure as the years roll by these issues will be ironed out. I'm hoping if I'm lucky enough to reach old age, by that time we'll have vehicles that'll take you from a to b with (genuine) minimal input.
