In the ARCA race yesterday one driver turned and crashed head-on into the wall during the pace lap, all by himself, before the race even began. I've watched a lot of races, but I've never seen that before.
I did once see a collision while the cars were parading during a caution flag. Bennie Parsons was asked later what happened and he said that the car ahead of him got sideways. Asked how that happened, at about 40 mph, he said, "I don't know." Asked why he then hit the car that was sideways he replied, "I didn't stop." Asked why he didn't stop his answer was, "I don't know." Aren't we glad he clarified that situation so brilliantly?
Jimmie Johnson was penalized today for speeding on pit road while serving a penalty for speeding on pit road. That's sort of like carrying a beer into a court-ordered AA meeting.
It should be pointed out that race car drivers mostly don't go to college.
