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.
