History is not the easiest subject for me.
5' is the answer. But tell you what, like anything else, test this in the court of law. You will be surprised. If your ticket doesn't say how far your car was parked, then the onus is on them to prove it..!! You take a picture of your parked car at that place. You will make a valid case.
Just pay the ticket the chances of a successful ligation for a parking ticket are slim.
