man, you took the time to write the post. I'll address just one point: >Furthermore, electric vehicles and the like don't help the situation. If your car suddenly gets 60mpg instead of 20, it's only going to ENCOURAGE you to drive all the way across the state to get that special jar of peanut butter you like, instead of walking down the block to the corner store. as a result, we need to build more roads to get you to your precious peanut butter; and the new roads in turn invite more traffic, etc. 1. electric vehicles will for quite some time be limited in range. 150mi currently feasible in $30K car would at best be 600-800mi if some of the promising research reach productization 2. the main limiting factor in the driving to get the butter is the human time. Most of the people in the developed countries value their time high enough. 3.wrt. "new roads" - it is a bit far fetched for today, yet for 2050 year can we assign at least a bit higher than 0 probability of "flying car" ? :)
