About six times in the Indycar race today one car hit another and caused a wreck. In each case the offending driver was penalized for "making contact," which I thought was rather amusing. The same thing happens about three dozen times during a stock car race, causing the targeted car to wreck about half of the time, and it is written off as "nobody's fault, just hard racing," or "just one of them there racin' deals." The offended driver usually returns the favor in a subsequent race, often with interest. Indycar drivers just whine to the media after the race.
A.J. Foyt, on the other hand, says that "There are a bunch of goddam idiots out there" when his driver is wrecked. The announcers later paraphrased him as saying "gosh darn," but the damage was already done.
