That would lead to ridiculously overengineered car doors. It's already incredible how such a simple thing like a door can be so unreliable on newer cars, with handles that sink into the doorframe when not in use, or a locking system that only works with battery power. I'm not sure that adding more complexity would be a net benefit for society.
It's already there, my new fancy car has it. Push the lever to open with electronic help, pull the lever twice for mechanical release. The electronic help version checks for safety first (as long as you do it with a timeout from when the car was running/ready) We'll have to see how the fancy car does over time, but I did get one with handles on the outside that don't disappear.
