Logically...arrested. The car breaking down, no matter when or where will cost me money and time anyway. Being arrested for something I didn't do could result in monetary award (besides, been there done that, not so bad really).
Would you rather step on a large nail sticking straight up from a board with your bare feet, or have a heavy duty staple punctured through your thumb?
the thumb, I like walking ... would you rather eat a duck or eat crow?
