What does yesterday's deadly car crash mean for the future of Indy racing?

Two-time Indianapolis 500 winner Dan Wheldon died yesterday after he was involved in a multi-car wreck at the Las Vegas Indy 300. Wheldon was only 33 years old and had a wife and two sons who were present at the race.

Following the crash, the rest of the race - the marquee event of the IZOD IndyCar World Championships - was canceled. The drivers, many of whom were visibly emotional after emerging from a meeting with IndyCar officials, did a five-lap salute in Wheldon's honor.
