You'd think after the first guy went off, they'd put a flag up or something. Then again, considering how looney European rally races are, and that the next car was probably going even faster than the first, I wouldn't want to be the guy who had to wave it.
No idea if these guys were OK or not, but I've seen people walk away from worse. Can't think of a better example of why real race cars use real roll cages, and why people who try to race real street cars on real streets are homicidal maniacs.
