In a victory for the University's tree nazis environmentalists everywhere, Ann Arbor mayor John Hieftje say's he's replacing all city buses with hybrid models within the next three years. Though they cost 85% more and only save 30% on fuel, this makes sense to John Hieftje because he says he'll save $2.5 mill in fuel costs over the next 12 years.

Here's a little trick I like to call math. Old buses cost $300K, new buses cost $550K, Heiftje plans to replace all 75 buses within three years.  So he's spending $550,000 x 75 which equals $41.25 million to save what was it? $2.5 million over 12 years?  I knew I took Calc 1 for a reason.

Look, I'm a fan of the environment and fresh air and all that, but $41 million for "green" buses? I'm pretty sure we could research and develop a fleet of robot-operated, magnetic hover buses for that much.
