It's been at least 4 years since I drove an EV so I don't remember what they do. I expect the car to slow down and eventually come to a halt. I remember that I wasn't surprised by anything in particular so it's probably what it did. What do Teslas do?
Teslas do aggressive regen braking when you lift your foot. And it's not possible to disable that behavior, unlike other EVs.
So-called single pedal driving isn't very familiar to most drivers, making it unsuitable for rentals where users would prefer not having a learning curve.
Also if you ask the community how to disable regen braking you'll be told that you're driving it wrong, see:
