Yes Torsten they don't race NASCAR cars in the rain. They don't have windshield wipers, and the tires don't have treads so as soon as there is any moisture on the track the tires start slipping, So they stop the race until they can dry the track. If they can't dry the track the race will run the next day unless they reached the half way mark, then the driver in the lead when the race was called wins th race.
