Tension surrounds IndyCar's annual stop at Texas

The tension surrounding Texas Motor Speedway began in the offseason, when drivers still reeling from the death of Dan Wheldon publicly questioned the compatibility of IndyCar and high-banked ovals. It's led to a conflict between a track promoter who has been a longtime IndyCar supporter and the stars of the series. When the checkered flag falls Saturday night, it could be the final time for IndyCar. Texas has hosted 23 previous IndyCar races dating back to 1997. At issue right now is safety concerns stemming from Wheldon's fatal October accident at Las Vegas Motor Speedway. The two-time Indianapolis 500 winner was ultimately killed when his head hit a post in the Las Vegas fence, although the style of pack racing on a high-banked oval led to his car going airborne.
