it's really not dangerous except in very specific situations. we're not talking about waving someone to let them pass in the middle of traffic, we're talking about driving through suburbia, coming to a stop sign at the same time as someone, and then waving to let them know they are free to go before you. illegalizing the literal action of that because some stupid people do stupid shit is insanity. the focus should be on the person that irresponsibly waved the pedestrian in a dangerous situation, not the action itself.
