Will the CEO of Digg make up his mind on who he wants to be? I once asked him what car he drove, and he took pains to let me know he had a suburban-dad Honda minivan and an environmentalist-standard-issue Toyota Prius. Just a regular guy! But he later complained when I suggested he wasn't a "rock star." I'm thinking Adelson — who commutes from his actual suburban-dad life in upstate New York to his CEO gig in san Francisco — is working on sexing up his image. A tipster says Adelson has just gotten a $109,000 all-electric, obsidian black Tesla Roadster. Which, if you think about it, is exactly the racy kind of vehicle most suburban dads his age might want to buy, if only they could afford it.

Details have emerged about the latest model of the Valley's most self-righteous ride, the 2009 Toyota Prius, which hasn't been significantly updated since 2004. It will reportedly be longer, faster and more fuel-efficient. Also, the range of available models is expected to grow — anything from a smaller coupe to a larger, Lexus-like luxury sedan. What's not mentioned?

In a blow to environmentally conscious socialists who espouse the frugal, sustainable sensibility of Cuban car culture, Salon's Pablo Päster has done the journalist math. It turns out that a brand-spanking-new Toyota Prius is more energy efficient over the expected lifetime of the vehicle than an old beater Mercedes from Daimler-Benz. What Päster doesn't take into account are alternative energy retrofits to classic cars, like MTV's pimping out of a Chevy Impala to run on biodiesel, like the one picture above. Because while a twee Prius might say "enviromentally conscious" to Stuff White People Like readers, Stuff White People Do readers (myself included) would much rather cruise El Camino Real in a biodiesel-fueled lowrider, mijo.
