whether or not the ****** is his (which i think it is) doesn't really matter, the man is sideways with one hand. while it probably makes it less impressive, i think it's cool that he's on rain tires.
the rains probably made it easier to do this stunt, as they spin up easier and at lower speeds, but it's not like it's easy to do even with rains on. it also begs the question, how wet is it?
