Horseracing already has the highest mortality rate of any sport in the world per capita to the people who do it. If you crash in Nascar you still have a roll bar, and a cage, and a lot of protection. It's built to crash, but if you fall off a racehorse we all know what can happen, so it's tremendously dangerous.
