I was nudged off the road the other Sunday by a driving school car. We had words me and the instructor and he told me (erroneously) that the law states that I, a cyclist, should be within 3 feet (in a metric province) of the side of the road. He reckoned that I was further out than that and therefore in "his" part of the road and presumably, logically he had a right to do with me whatever he chose.
Therefore: if in your mind a road belongs to cars by law anything not a car is outlaw and subject to whatever justice you deem appropriate.
