It depends. My fiancee has it and it's been under control for years and she takes medication daily for it. Iirc in our state if you haven't had a seasure in 2 years you can get your drivers license.

The version she has isn't the movie kind either, she's fully conscious and relatively in control while it happens. She would have time to break and chuck it in park before it gets to the point her body doesn't cooperate and even then she can still speak and talk people through helping her, assuming she's not with me or family who knows what to do. She carries a special suppository gel that'll stop it. Imagine a smaller prefilled turkey baster, or bigger lube injector.
