We don't make a practice of showing crash videos for their shock value, but this vidcap of the SPEED Channel broadcast of the Grand American race at Mid-Ohio is worth checking out for a couple of reasons. (Yes, BMW driver Joey Hand walked away from this amazing crash.)
First, the law of unintended consequences. Hand's BMW was lightly tapped by Paul Edwards' Pontiac as Edwards took an optimistic look down the inside as he battled Hand for the GT class lead late in the race. Hand slid to the grass, saved it, and looked set to take a shortcut across the infield when a newly-constructed access road (probably slightly elevated above the grass for drainage) launched his BMW end-over-end across the track.
Second, what a testimony to the remarkable strides in racecar safety. Hand's cockpit roll cage remained completely intact through multiple high-speed impacts, leaving Hand stiff and sore after the incident, but without even a single broken bone.
