I really like Tesla's approach to door handles - it's clean, polished, and gives a fine and smooth look. But was surprised to learn that China will ban them beginning next year. Other countries might follow suit as well.
The main purpose of a handle is to open a door, not look polished. Looking polished is not helpful when you're dead because you couldn't get out of that car in an emergency . So IMHO it shouldn't be surprising that they're being banned.
I'm convinced it isn't rocket science to design a flush handle that looks as clean yet has a manual operation fallback (preferably mechanical). Eg. Something like an integral hinge where you can push the short, base end in to pop the release (provided car is unlocked).
IMO their handles are stupidly over-engineered. It shows when you get problems like ice, etc. in northern climates.
