 FACT: Joe and Jimmy could not have taken the race cars from the  party as easily as they did. CART cars do not have onboard starters,  so they cant be started simply from the cockpit. You would need a  crew member with a starter motor at the back of the car to fire the  engine.  Most "racing cars" at shows and parties like this are usually dummy  display models, without "real" engines or other heavy, and  expensive, mechanical components. Moreover, if the cars actually had  been authentic (and somehow could have been started), they likely  would have had virtually no fuel aboard; most city fire departments  have strict regulations on this for a show or display car,  especially inside a hotel.
