This reminded me of something a friend of mine, who was a NYC cop, told me years ago. In NYC if a car is parked in front of a fire plug , and the Fire Dept gets a call there, and needs access to that plug, they will either break the windows and run their hoses through the car, or up end the car on its side, and slide it metal to asphalt, out of the way. Before the police ticket the car and tow it. Not exactly on topic but just came to my mind. BTW, I wouldn't consider that being 'boxed in.'
