According to a January 2008 Associated Press article, it was announced that Priestley would become a joint owner in a new IndyCar Series team. The new team was known as Rubicon Race Team managed by co-owner Jim Freudenberg. They initially entered a car in the 2008 Indianapolis 500. The car was prepared by Indianapolis-based Sam Schmidt Motorsports and the driver was Max Papis.
In the article, Priestley said, "I'm excited to be able to spend the month of May in Indy with my good friends and be a part of the greatest open wheel race," "It's been more than five years since my accident, and it's going to be so good to get to see everyone."

Lead singer, Ed Robertson, continues to cite him as being instrumental in their American success. His final notable contribution to the band came when he directed a feature-length documentary about the band's 1999 whirlwind of success titled Barenaked in America, intending to capture on film the fun he had while riding around on the tour bus with the band.
