Hollywood celebrities will drive Toyota Priuses precisely long enough to realize that they are environmentally friendly shitboxes, and then they will retreat to their BMW's and Range Rovers precisely as Ms. Anniston did. You have to give them credit for living the life of the common man long enough to show us the way to environmental nirvana, though. Owning a Prius will essentially become a way for celebrities to relieve themselves of the guilt of owning a stable of other 4 wheel indulgences. It doesn't matter if you actually drive the Prius, as long as you can point to it in your driveway when you start getting heat for taking your Hummer out shopping on Rodeo drive. Toyota knew what they were doing when they marketed these cars to the Hollywood elite; guilt is a powerful incentive.
