This morning I saw a guy trying to drive his car out of his parking space. He had to attempt to do this 8 times before he decieded to get out and try to shovel the small mountain range of hardened slush out of his way so that his car can get on the street. The surprising thing is that the small pile of frozen slush was only about 8 in. tall and about a foot wide. This guy was driving a fairly recent car, but I will bet he has all seasons tires that are about 60% worn out. Imagine looking into your rear view mirror and seeing this jerk flying towards you with a surprised look on his face when he could not stop in time.
