I would argue stuff like electric adjustable mirrors, seats, good AC, parking sensors, rear view cameras, even automatic transmissions are essential safety features these days. If you put a modern person in a car lacking modern features they're going to be a hazard on the road.
I do appreciate electric mirrors and air conditioning, but the rest of this list is pretty hard for me to buy. I think I'd be called a 'modern person (and one of my cars even has most of these things!)
