I'll be the first to admit I don't work on cars so as an ignorant fan I don't know but it's easy to sit back now and analyze the situation in the aftermath. In real time as a fan, when you see your favorite driver since grade school crash like that, you aren't thinking rationally. Fear sets in. Hit in the driver side door after going airborne and landing on the asphalt, slide down the front stretch and car in flames with liquid pouring out and not moving afterwards. Your gut instinct is to be scared as hell and hope he is okay. The only hope I had is seeing scary crashes before with drivers walking away but that doesn't always mean the same impact on the driver like with Earnhardt.
