For the people who feel bulletproof with all the safety equipment available these days....look closely at this pic...this driver clearly has a full containment seat and some sort of head&neck restraint...but his arms came through the front of the cage hard enough to knock the sunvisor off. ..and it appears that his arms are the only thing keeping his helmet from hitting the front crossmember of the cage...no matter how secure you feel before you throw that un do-able slider please remember that belts stretch under severe loads, bodies stretch, and you are for sure not bulletproof
