I think Nascar should supply rain tires and require teams to have wipers on the cars in case of rain. Everybody else does it, why not Nascar? That would throw a whole new level of racing into the picture. I bet some of the guys you don't hear much from would show the others a thing or two. Heck, guys race freaking motorcycles in the rain. You already have guys that are good on short tracks, guys good on superspeedways, road courses. I'm sure you would see guys stand out on a wet course too.
