Unless the racecar is run by remote control, there will always be risk and death. Regardless what safety equipment added, anytime you take a machine or a sport to its edge, it can and will fail. sky divers, motorcyclists, aerobatic pilots, mountain climbers have deaths every year. Risk can be mitigated, but not eliminated. I drove a front motored dragster for years. Scary, sometimes yes. Risky, you bet, Dangerous? of course it was. Fun? Damn right it was. I had people shake their head at me and say "I would never get in one of those death traps". Didn't stop me.
