Saving the world one taxi ride at a time

Hey, for all you peeps down in San Fran check this cab company out.  Whenever I'm in the bay area it's all I use cause they're trying to make the world a better place.  Well... truth be told Microsoft has a limo for me but I'm going to have them paint it green and make it a hybrid.  How cool would that be?  Maybe I'll even get one of those hummer limos and turn it into a hybrid!  You know people, it feels good to help save the world, even when you're running it; or dare I say driving it.
