I know the arguments for cycling more, and I agree with most of them. However, I drive on the North Circular (in London) to go to work, and almost every other day, during rush hour too, there's invariably a cyclist there who makes driving really dangerous: everyone has to change lanes quickly (there's no space to pass the cyclist while remaining in lane).
So: am I being unreasonable to feel cyclists just shouldn't be on high speed roads as they make driving conditions there more dangerous than necessary both for them & for drivers too?
