Today on the Streetsblog Network, member blog Riding in Riverside sets out to explode the myth of the “wundercar” — a vehicle powered by sustainable fuels that will allow us to hold onto our driving lifestyle and all its accoutrements, while saving the planet and feeling “green.”

That kind of futuristic fantasy isn’t going to solve our problems, writes the blog’s Justin Nelson. The answer, he argues, lies instead in older patterns of development and mobility:

This is not an environmental silver bullet. (Photo: bindermichi via Flickr)

[E]ven if we were to devise a perfect car, one made out of recycled tires and printer paper, one that harnesses photosynthesis to not only be carbon-neutral, but actually make energy from atmospheric C02, even if we could make a car with no direct environmental impact, it would still be an environmental and social disaster. Our waterways are contaminated by engine fluids and lubricants that run off of road surfaces. Our natural groundwater tables are falling because rainwater is unable to penetrate pavement.

Cars still allow sprawling development that eats up wild lands and spits out bland suburbia. Species’ ranges in the few precious areas of wilderness that we have are disrupted by highways. We would still live in a society where we shut ourselves off from one another in our own private boxes, promoting inequality and a lack of respect for shared humanity. We would still leave our inner cities to dangle. Our streets would still be unsafe places for children to play, and we would still kill thousands every year in automobile crashes. Alternative fuels are, on a perfect day, a solution to only a few of the myriad problems that cars cause.

On the other hand, instead of pursuing unproven technologies in a desperate last-ditch attempt to hang on to the way of life we’ve been living for the last 50 or so years, why don’t we look ahead and try to build a better world… Instead of a risky gamble to maintain a failing lifestyle, we should spend our resources on forging a bright future based around principles of city-building as old as cities themselves.
