If the "very easy to work around" requires some mechanical / electrical skill and getting under the car to work on it, it would probably at least stop them from being used as an impulse weapon? Like, it's hard to keep a dedicated person from killing themself or others; it's a lot easier to keep someone from doing it on an impulse, which is how many suicide attempts, and I think a number of the "driving into a crowd" terrorist attacks happen.
