All told, Americans spend $489 billion annually on gasoline. Every 25-cent increase in the price of gas costs households $90 million per day. That’s hitting a lot of Americans very hard, especially right now as real wages stagnate and unemployment levels remain high.
And no, it is not about building more roads to reduce traffic so traffic flow and therefore the engine becomes more efficient. It is not only about building/buying more efficient cars because the amount of paving, parking, and time lost to traffic and commuting is also at issue. It is about reducing demand. Although demand implies that this is something we want, which it isn't. People want choice. The current road/city building is not about choice nor freedom as American Dream Coalition and other crooked hacks will have you believe. Choice is mode of transportation and possible routing because there are a number of options and destinations within reasonable distances.
It is about reducing our mandated need for spending our entire lives in the car where everyone else on the road diminishes the "ideal" road condition, where everyone else on the road is the enemy. Not only does it harm the economy, but it can't be good socially either. That's one of the big reasons I gave up my car. I was tired of getting out of it angry every day.
