Yesterday at the WeatherTech International Challenge vintage races, a Shadow DN-4 Can-Am car driven by Jim Pace suffered a blow over crash on the main straight at Road America. While the Shadow is essentially destroyed, the good news is that Mr.Pace walked away. One report was that the crash was at 180mph, but others familiar with the track and the cars say it was about 140 mph. The report also says the car slid 150 yards on the roll bar, but it looks a hell of a lot longer to me. OTOH, I have never been there.
Note the left front tire is off the track in the second photo.
