I believe that it happens far too often for big series like CART and IRL and even F1.
Sure we can be comfortable in the knowledge that it is nearly 12 years since an F1 fatality, but it should be 24 at least.
There must be a way to make these things safer, whatever angle the car crashes at and at whatever speed, even if that means reducing the overall speed and therefore spectacle.
Well since Dale Earnharts death as well as Sennas death, those respected series have expierianced no fatalities. Nascar has introduced many saftey features as has Formula1. CART and the IRL have not really changed anything
They benefit from running on tracks where Nascar races as well, so they have some tracks with safer barrier walls. Even though race car drivers know the risk. When I raced cars and flipped over 2 1/2 times and came out bruised and shaken, I did not give up, but kept on racing, knowing I was fortunate. Racers don't think about death even though its a very real thing. All these drivers that have died all know the risk they take. Do we want to see more deaths, No. You would have to be sick in the head to want to see death. Is this the last death we will see. Lets pray so.
This is all we can really do.
To finish first, first you must finish.
