Bikes & Cars...

Now that peaking gas prices are giving drivers more incentive than ever to consider the alternatives, it's a good time to review all the celebrities who have already taken the plunge with the most famous alternative: the Toyota Prius hybrid.

Among the first famous Prius drivers is early adopter Leonardo DiCaprio, who's been driving one since 2001 when they were new. Then Cameron Diaz got one. Then, like, EVERYBODY got one. "Everybody" includes usual green and/or lefty celeb suspects like: Alicia Silverstone , Arianna Huffington, Brad Pitt, Julia Roberts, Bill Maher, Prince Charles, Woody Harrelson, Harrison Ford, Ed Begley, and Susan Sarandon.

But now the Prius is common enough that less-expected Prius owners in Hollywood number easily in the dozens (maybe more like hundreds), including Kevin Bacon, Jack Nicholson, Billy Crystal, Larry David , Ewan McGregor, Robin Williams, David Duchovny, Alexandra Paul, America Fererra, Billy Joel, Dr. Andrew Weil, Ted Danson, Will Ferrell, Salma Hayek, Patricia Arquette, David Hyde Pierce, Ellen DeGeneres, Tom Hanks, Rob Reiner, Hart Bochner, Donny Osmond, Kurt Russell, Jack Black, Donna Mills, and Kirk Douglas. The jury is still very much out on whether the Prius is the best (or even a good) green car option, but it is certainly the most recognized.
