Isn't Tesla touch handle doors? Not sure who else has them. Not sure what benefit they add anyway. I'd imagine there is some sort of manual override for when the 12v system dies and you can't get into the car?
My guess (based on living on a dirt road which gets everything in a vehicle coated in a layer of fine clay dust) is that it reduces the number of water/dirt ingress points so the door lock lasts longer.
I've had to take the door panels off two vehicles now to clean dirt out of the locks to get them working again.
Not all of them. Model Y's and I think 3's you push on the big spot and that pushes the lever out to grab. I think it might only be the higher end S and X models that have the handles pop out electronically.
