If you are driving a smaller car, which is what I take a supermini to be, give rides to strong passengers. One starry night on the beach at Acapulco, we simply clean and jerked the rear end of a VW beetle out of the ruts it had dug, and went on our merry way. That VW bug was a great car - if the battery was dead, you could always push start it with no problem - keeps the driver in good shape.
