G-Cars

I'm kind'a scared with Michael's driving around San Fran. He uses the G-Car (Gravity Car) approach, aka driving with the car engine off and in neutral gear at every minimally downhill inclined part of town and/or when approaching red lights.... However, not being REALLY sure of how much we are diminishing our Carbon Footprint by this very sketchy alternative style of driving, I decided to check out in Car Talk on the efficiency, and reasonability of this 'style'. Lo and behold! a complete discussion on the topic ! (http://action.publicbroadcasting.net/cartalk/posts/list/2131561.page)... Whatever your conclusions are, the site is still hilarious, and has some good advice... Michael, Be careful! Save CO2 emissions some other way!
