NASCAR Racing: Nascar Drivers and The Call of Nature, nascar drivers, defacate

Question
How do NASCAR drivers urinate or defacate during the long race? Is the some kind of device? Please tell me everything you know about the subject! Thanks!

Answer
Well, suprisingly enough, I get this question more than anything. Basically if they have to go, they hold it. If they can't hold it, they "wet themselves". Usually it isn't an issue, because they sweat out thier liquids before it makes its way to thier bladders. There have been times when drivers have gotten sick to thier stomachs, and pulled into pitroad. Dale Jr did it once. Usually if it's a matter of urinating, it's not an issue, if they get sick, they can pull their car over if worse comes to worse, and like I said, it has happened.
