Johnson says he was glued to his television Sunday watching the coverage of Indianapolis 500 winner Dan Wheldon’s death in the IndyCar season finale at Las Vegas.

Johnson believes the IndyCar cars are built for street circuits and road courses, and drive too fast to race on ovals. He says the car is not built to withstand the bumping that occurs on ovals.

Johnson was in his own frightening accident Saturday night at Charlotte Motor Speedway, when his car hit headfirst into the wall. The back wheels briefly lifted off the track, but Johnson walked away and suffered only next-day soreness.
