Actually, it usually happens only in open wheel racing. The front tire of the following car must make contact with the rear tire of the leading car....and the tires are only exposed like that in open wheel racing. It happened a few spectacular times in F1. The most memorable being Montoya and Villeneuve around 10 years ago. The resulting flying wheel killed a marshal. It's happened to me kart racing, unfortunately, the person didn't fly over my, but the front of the kart landed on my helmet and then fell off the back.
