Exactly that. If the youth of america doesnt prove this already, we are all doomed. Young kids would rather look shit up on their smart phones and think they know everything, than go out and actually try to figure it out on their own. Same with these driving aids, its one less thing oblivious drivers feel the need to think they need to pay attention for.
Back up sensors, IE the audible ones that are installed on the rear bumpers in 2-4 spots are AWESOME though. You can watch your mirrors (as you should be) and when you think you are close enough the chime goes off telling you if your assumption was correct or not. Thus TEACHING the driver how long the car is, how to use the mirrors correctly and what objects look like in them based on proximity.
