Video: Big wreck in IndyCar season finale

The wreck that injured Justin Wilson. He hit one of Fontana's infamous seams. Why is IndyCar racing at a track with such seams in the asphalt and why is their season finale at a track where the grandstands are mostly empty making the series look like a loser? Curious minds want to know why the season finale is not at the Indianapolis Motor Speedway before 100,000+ fans instead of 20,000 in Fontana on a track with a surface that causes crashes and so much debris the teams need a shop-van to clean out the radiators during pitstops? Well if you watch racing for crashes, then Fontana is your track.
