IT's not. But my point is that you still need cars for the other 5k++ miles. I'm not saying that bike riding isn't nice, merely that it is not possible for many, many people during many, many parts of the year.

Okay, some hipster with two young kids can take a saturday jaunt on a super-long, super-expensive electric bike, but that's not going to work for most people when it's cold, dark and rainy.
