I've been thinking about the transportation issue. Self driving cars may or may not be widely available by the time they are finished. But they could bypass it all just by building sensors into the roads, or just tracks. You could then have a system of self driving busses that people could order with a smartphone, and then find the most efficient route to get everyone where they want to go. And then you have minimally congested streets that are very pedestrian friendly. In fact you don't need self driving vehicles to accomplish this even. A human pilot following instructions from a computer that calculates the optimal route. The point is you can get public transportation without the downside of fixed routes. Anyway, along other recommendations people have given, look at this site. I've always been fascinated with it: http://www.newworldeconomics.com/ http://www.newworldeconomics.com/ Especially this article on Toledo, Ohio vs Toledo, Spain: http://www.newworldeconomics.com/archives/2010/022110.html http://www.newworldeconomics.com/archives/2010/022110.html
