The video idea is good. I'd talk to a lawyer before you loose it. So far he is speeding, driving recklessly and disturbing the peace. So far you have committed assault with intent. Don't let him get to you. This might be a instance for a restraining order on him, see a lawyer if the cops won't respond.

Plan B is to organise your neighbors into a mob and deal with him, remember there is safty in numbers.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats. H. L. Mencken
