Solid concrete and carbon fiber/moly tubing do not mix-especially when hit head on
In most cases walls are safer than the old guard rails that could slice and dice you. I rolled on a guard rail in 75. I was super lucky
Check out my 71 White Comet Pro Stocker on my Career Gallery. www.animaljimracing.com . Last two pictures on page 1. The nose rolled along the gaurd rail twice--then car popped up rolling high and came down rolling on gaurd rail again right behind the driver door-while I was still hooked to loosened belts and my body being slapped to the ground like a rag doll on the last 6 rollovers of 12. Lucky I was not sliced to bits by that guard rail. I have the video. If you saw it-you would not believe I was alive.
