I could imagine how you could make an entirely electro-mechanical setup to handle the Tesla doors, and probably make them more reliable in turn.

But yeah, everything being controlled by a computer is becoming more and more common.

For the Ioniq 5 and EV6, the computerised portion is not required though. On the lower trim levels the door handles are simply spring loaded, and you have to push the front of the handle, to lever it out to grab. On the higher trim levels there's a motor to push the handle out, but it's still just spring loaded, so nothing is stopping you from levering it out just like on the lower trim levels. Pulling the handle is exactly the same as pulling the handle in any other car, it just mechanically opens the door. And there's a fully mechanical lock as well. The door handle on the inside is also entirely mechanical.

Here you can see how the handle and lock works if the car is entirely dead (at 1:38) https://youtu.be/Lv6wwn8m-8U&t=98

I like how Hyundai have managed to add all the nifty features and conveniences with electronics and computers, without compromising the mechanical reliability.
