I hired a car in the States once and got seriously pissed off with the safety features. Get in the car, put the key in the ignition start it up and drive.
Not being told to put on safety belts, lock the doors, put your foot on the brake before you put it into drive.
Plus many other ones that i cannot remember.
There seems to be a current trend for cars that don't start unless the clutch is engaged.
First discovered the negative side of this pushing exMrsF back and forth across a car park in the early 90s as she had run down the battery having left the lights on.
She would not believe me that this feature would prevent a bump start until it been tried multiple times.
The nice man from ADAC started it in seconds with his power pack.
On the subject of rear view mirrors, I once worked in a Lexus dealership and we had an unusual Jap import in.
I drove it around a lot and all of the buttons were in Japanese script, I worked out what most of them were, but one intrigued me for days.
When you pushed it there was a noise that was high pitched and squeaky but I could not tell where it came from.
One day I was reversing into the bay and it was really p*ssing it down, still baffled by this mystery button I pushed it again and as I did all of the rain just dropped off of the side mirrors.
Some sort of ultrasonic wizardry, very clever stuff.
