After reading the responses to my thread "Why don't cyclist's know the road rules!", it got me thinking that some cyclists may never have been taught the road rules. If they have never driven a car, it's fair to assume that they have a concept of the road rules but have not been taught them properly. Is this why we see so many cyclists doing dangerous things. It stands to reason that a cyclist who also drives would make a safer cyclist because they have had formal driver training.
