I watched the Montreal F1 race and when the accident happened I thought the worst. Glad to see he's OK, after surviving a 75G hit! I thought that was impressive until I read about David Purley - 173kph to 0 in 66 cm - 178G!!!!Unbelievable!! And that was in a car that would be like a cardboard box compared to the strength of today's cars.
