I can add to #1 just because I have asked someone who does this why the fuck he does it. He doesn't put the helmet on the side though, it is under the cargo net on the back seat area... he rides without the helmet during the day but puts the helmet on at night when his head gets cold... I'm not shitting you either. Oh, and we even had bicycles wave at us yesterday... we got a good laugh out of that and decided they must have been drunk (either alcohol, or by just seeing a couple thousand motorcycles at bike night).
