I don't have any reason to believe a paranoid schizophrenic capable of buying and maintaining a scooter is going to be any more persuaded to use public transit than anyone else. They are going to use alternatives for the same reason the rest of us do. The ones using public transit are generally the ones with functional issues to the point they can't even get to that point of having a functional e scooter to crash.
