Rahal questions Wilson's penalty

After replaying his brush with the wall over and over in his mind this week, Graham Rahal takes full blame for the mistake that almost certainly cost him a victory at Texas Motor Speedway last week. Heading into Saturday's IndyCar race at the Milwaukee Mile, Rahal does wonder whether Texas winner Justin Wilson deserved a more significant penalty for a technical infraction. Wilson took the checkered flag after Rahal touched the wall in the closing stages of the race; Rahal recovered to finish second. A post-race inspection found unapproved pieces of bodywork fitted to Wilson's car, and Wilson was docked five points while his team was fined $7,500. Rahal says, ''When is cheating cheating? Oversight or not, it doesn't matter. It's illegal.''
