The race preceded a mass exodus of significant drivers and teams who all competed in their final Champ Car event, most of whom knew beforehand that they would not return.  Most rued the fact that they were leaving for the rival Indy Racing League, wishing to continue in CART rather than endure a more stable future in the IRL.
