FYI, I only attempt to prove people wrong when they are. Oh yeah, and you are correct about why carpet is in a car. But just because that is why it is there does not mean that it doesn't do other things also. In addition to the three afformentioned things, it also gets stained and torn. Oh and by the way, I am not the only one stuck with ideas. Just like in the movie, "If you build it they will come," "If you make the box right, it does not rattle."
