How many things are illegal and not enforced? How many times have you been out on your bike at 5 mph over the limit and not get stopped. Are you breaking the law, but then who makes the choice not to stop you? Or will they show up 10 years later and say you did a no-no back then? Are you in a fit of guilt going to turn yourself in and pay a fine for speeding 5 years ago? See my point?
