>Why not go a step further and demand that all roads should be put underground, too, so that pedestrians can enjoy an idle stroll on green meadors above ground without all the annoyances that come from car traffic? I'll do you one better! Since the cars are going to be electric, why not put charging inside the road, so that the car would charge while rolling? In fact, we can forgo the battery entirely, making the cars lighter, by powering them through the road! While we're at that, we could allow cars going to the same destination to link to each other to optimize traffic. Oh, and we could also reduce rolling friction by putting these vehicles on rails. There you go, we could do much better with underground roads on which electric vehicles roll on rails in metropolitan areas. We could call these system metros. Ah, if only such utopian dreams could be implemented. I guess we'll never see it in our lifetimes.
