I know a fellow in my neighborhood, the neighbors of whom could benefit from him sticking a bigger engine in his obnoxious Hoveround. When he runs errands with it, he drives it down one of two traffic lanes on Kentucky Avenue, seemingly oblivious to the parade of automobiles that is trying to get around him without causing any more accidents than Indy is already subject to on a daily basis. Through some miracle, this man is still alive.
I say: Take off the orange triangle (its not telling us anything we don't already know, add lights instead) and put an 80 cc two-smoker back there. Add the right rear sprocket and a centrifugal clutch, and that thing should do more than just hover around.
