Clearly you're an idealist. I don't mean that as an insult. The problems you've brought up can be solved by other means while retaining the existing infrastructure. For example, you could have cars that are non-oil-based. You could increase the amount of telecommuting allowed by the workforce. I would think those things are more likely in the US than making everyone ride a bike.

Your vision of the future basically kills every suburb and urban area and would reduce humans to extremely high population densities in highly concentrated areas. Leading to problems of it's own. But we're really off-topic at this point.

Interestingly enough, you said above you are in chicago. The area I am talking about above is in the western suburbs of chicago.

For example, you could have cars that are non-oil-based.

Not really a solution. The problem is the sheer energy required to move a 1-2 ton steel cage, not the specific source of that energy, though petroleum is an especially bad one.

"You could increase the amount of telecommuting allowed by the workforce."

While that would help, it would also be useful if you could, for instance, buy groceries or really just leave the house without having to bring the steel cage with you.

"I would think those things are more likely in the US than making everyone ride a bike."

The current infrastructure policy in the US can be described as "making everyone drive a car", even if they live in cities which are easily large enough to make other solutions more practical. I don't want to make anyone ride a bike--but I sure want to allow people to safely ride bikes if they so choose, maybe even encourage it.

The suburbs were created 50-60 years ago in the era of cheap petroleum and post-war infrastructure development. They aren't anything important to be preserved or saved--for various reasons it would be more accurate to view them as a failed social experiment.

Hopefully, when we do move away from the internal combustion engine we will move to something lighter. Currently the batteries are the source of massive weight for electric cars but we're all hoping that improves. We will (hopefully) have cars that are much lighter, more efficient, and based on some energy source than oil derivatives.

It just seems that that path is more likely than everyone in the suburbs giving up their homes and communities and moving within biking distance of home and work. I support initiatives that allow people to safely ride bikes. What I don't particularly like is expecting multi-ton vehicles driving at high speeds to negotiate 1/10th ton people going much slower speeds. There has to be a better/safer solution.
