But remember that you are also burning fossil fuel if you own a car and leave it parked in the driveway. I've read that just the manufacture alone consumes the same energy as driving the vehicle 55,000 miles.
I think the calculator is geared toward people who own cars and trucks, like me. It's clear that not owning/driving a car is better for the environment and your wallet than owning one, but I think this is a case of not letting the perfect be the enemy of the good. If a driver of a car wants to drive it less, he should be encouraged for doing so rather than chided for driving it at all.
