Motorists of this breed are nothing more than bullies and cowards. We all know that, right? Remonstrating with them is truly pointless, as in their minds it only reinforces their sense of superiority -- whiney cyclists thinking they deserve roadspace. So you either ignore them, and live with it, or get right in their face and make it clear they are dealing with an adrenaline charged unhinged nutter who's ready to go toe to toe anytime they are. I tend to savour the look on their face when they realise they are in trouble here, and that ton of metal does not make them the hardest kvnt in town after all. I also believe that next time, they'll think twice about their hierarchical assumptions.
