Used to drive commercially, was taking a load into Manhattan Island. You need a route slip to deliver there and you only have certain hours and you must stay on route. Well, an accident on my route closed a bridge that I needed. They set up a detour, long story shorter, I ended up on a road that I could not get around a sharp corner onto a different bridge, backed up traffic miles!! Thousand dollar fine, they said I should have waited till the route was open, even if I had to wait all day. It was God damned mess!!!! That cured me of unknown towns....
