We have limitless solar energy and enough nuclear technology to atomize the earth, but our motor vehicles still use fossil fuel. Cars are made with steel, iron, and plastic. You can't pick them up. Bicycle manufacturing is not controlled by special interests. Their goal is to produce the best vehicle possible.
Bicycles are the perfect synthesis of body and machine.
Be a cyborg. Cars on the other hand, are the epitome of special interest controlled products. The oil industry wants cars to get the worst gas mileage possible. The steel industry wants cars to be big and heavy, ostensibly in order to be safe. So, reject the greed of huge multinational corporations.
