It was only a matter of time before a thread about NASCAR degraded into bashing.
Anyway, hitting the wall at anywhere over say 40 mph on the drivers side is a HARD HIT, trust me. I drive NASCAR modifieds and I hit the wall almost head-on at about 70 earlier this season, and it rang my bell pretty good. And that was with the entire front of the car to absorb the impact. On the driver's side, there isn't much there, so your body takes a lot of it. Believe it or not, a crash like Dale Jrs could have been potentially fatal a few years ago. There has been massive advances in safety in seats, harnesses and window nets the past few years since Dale Sr died, which have saved more than a few driver's lives.
