Like someone else said, I think they have safety stuff as good as they can right now.
I've never raced, so maybe I'm off, but everyone knows that there is a chance they can wreck their car, opponents car, or even die doing this. But people are still going to do it because it's exciting. Just like sky diving, I'm guessing you think people should do that and land in a field of cotton and wear pillows .
But I've never raced on a track, so maybe I'm "off".
