Dear Mordichai, The video below explains why IndyCar had to reduce the number of oval races on its schedule. The crash and bodily damage was horrific. As for who should be held responsible? Well there are a lot of people to blame, including the greedy car owners who jumped ship to the IRL, but the primary architect of the biggest mistake in the history of auto racing, Tony George, has been fired by his own family, which underscores how they feel about what he did. Someday a book needs to be written about just how much damage he did as we don't believe people realize the extent of the travesty. The IRL is trying to recover, but we're not sure the damage is reversible. Maybe. Mark C.
