Where do some drivers get this attitude? It's clear to anyone with half a brain there isn't much space but oh no..closer..closer..closer until..oh look I'm practically welded to the back wheel. Such drivers need a refresher course not just in driving but also common sense - included in that course should be footage of what happens when you run a cyclist over and they end up under your wheels, through no fault of their own. Piss-poor standard of driving if you ask me.
A good example of "Do not get involved". You could see he was driving like a knob, go passed him and forget it without sounding your horn. Thne you have no problem.
