This year's LA Auto Show has been fertile (carpeted convention center) ground for perspective-shifted automotive announcements. While Toyota's Camry Hybrid was dubbed best green car, Saturn and GM sketched out plans to bring a plug-in hybrid to the market. The not-too-shabby-but-could-be-better numbers are in on Saturn's 2007 Aura Green Line hybrid, as well. And although Arnold did show and gave his benediction, the anticipated announcement of a new biofuels initiative did not come. Tesla's electric roadster gets a good ride around the block over at, and now that we know how much climate change potential there is sequestered in our love handles, TreeHugger passes along some useful tips on quitting the bike-riding vice.
