Don't get me wrong, I think bikes are terrific. I own several of my own, including a trendy mountain style, and ride them for pleasure and light exercise.
The automobile, both a cause and an effect of this decentralization, is ideally suited for our vast landscape and our generally confused and contrary commuting patterns.
The bicycle is a former child's toy that has now been elevated to icon status because, presumably, it can move the human form from pillar to post without damage to the environment.
