The environmental angle is only one part of the story for bikes vs cars. 1. Cars make you fat. Or at least, they certainly don't help. A bicycle (or transit) commute serves double duty as a commute and as exercise. 2. Cars are damned deadly. Drivers kill an absurd number of people for absurd reasons. You'd have to be exceptionally unlucky to be killed by a bicyclist. 3. Cars are expensive. For everyone. Even electric cars. Roads don't maintain themselves and asphalt's durability doesn't have a difference between a 1 ton Tesla and a 1 ton Ford. Also, you need a lot more asphalt to handle the same capacity. And that's just the public cost. 4. Cars are still expensive. Amortize out the up front cost, the interest, excise taxes, registration fees, repairs, fluids/filters/brakes. Even electric cars have a significant annual cost.
