they take shifts so when they need to go to the toilet they switch drivers ^ they do not take shifts they take the needed precautions before the race and if they absolutely have to they go on themselves
Race car drivers almost never have to urinate because racing dehydrates the driver. A far greater issue for drivers wearing multi-layer racing suits, gloves, and helmets in a hot cockpit is maintaining hydration to replace fluids which are sweated out rather than expelling fluids. Typically, the last two things one does before climbing in a race car are (1) go to the bathroom and (2) take a large drink of fluids.
While in a race they just pee. I do not know if they wear a diaper or other waste containment device but I do know that they don't hold it and that they don't leave their car to visit the bathroom.
NASCAR drivers usually stay out of the public eye behind the scenes before the race. Sometimes they are doing interviews, making sure they have been to the bathroom and talking to their friends, owners and pit crew.
Somebody from ask.com says that they sweat it out because it is so hot in the cars and they can pretty much sweat out all their liquids. But if they go, they just have to go, fire suits can be washed. They go before a race. There is no way to go in the car. If they really have to go, they just go down pit road and stop their car and go to a normal bathroom. But I've never seen it happen.
Usually it's 130 to 140 degrees in the car. You could sit in a sauna and drink all day long and not go to the bathroom. That is pretty much what happens with the drivers because you are in such a hot environment. And in the rare occurrence that they have to go, they just go in their suit.
There are many benefits of having race car drivers. These race car drivers are very good at providing cheap entertainment to many people for example.
