There are some people, like myself, who watch racing (in my case, motorcycle racing) for the skill and mastery, the sheer beauty of the sport, not for the wrecks.
Tire technology simply can't keep up with with the power being put down by the engine builders. Don't foget the Indy 500 this last year, where the Michellin drivers weren't allowed to race. This was also seen last year at the tire testing for the (motorcycle) Daytona 200 race. The Superbike class is simply too powerful for the tires available on the superspeedway portions of the track. Last year there were two "catastrophic tire failures" (separations or blowouts), one at over 185MPG, the other at over 190MPH. Needless to say, both riders wound up in the hospital.
Because of the danger, the Daytona 200 "banner" race was switched from Superbike to a different, less powerful class of bikes, and the Superbike race was shortened in order to make it safer.

That wasn't the Indy 500. That was F1's Indianapolis Grand Prix.
