A few comments
My usual car , a Ford Mondeo/Fusion has several auto features like lane warning, parking sensors, speed limit detection, auto stop start etc but not auto park. They all work but are unreliable. Maybe that because it is a "cheap" Ford but none of them are good enough to use as AV sensors.
The lane departure will trigger if you change lanes smoothly, the auto S/S is OK but I switch it off when there are lots of roundabouts/traffic circles because it will shut the engine down just as you move forward leaving you stalled for a vital moment at times.
The auto wipers/lights are a bit slow to react . They dip fast but are slow to go back to full beam. The adaptive LED lights are fantastic though, espeically for older eyes.
The parking sensors are useful but have one terrifying fault. Once my wife was driving in very heavy spray at 65 mph amid trucks etc. Safe but needing full concentration. Suddenly the parking sensors triggered giving her quite a scare. I was able to re-assure her but I think for an inexperienced motorist such a noise in heavy spray is not very safe.
Also on auto S/S one potential issue is main bearing wear as the crank stops. sinks through the hydrodynamic oil film then is suddenly rotated many times per day. Maybe not an issue with modern oils but worth thinking about with new engine at thousands of pounds these days.
None of this is a reason not to have them but I don't think they are yet anywhere near "fail safe" Also I have just been driving three different rental cars in a week. There is a real problem now in that no rental car has handbook and all have different auto feature approachs. Trying to work out how the car operates in the middle of navigating unknown cities roads is not as easy as it was in analogue days.
