i'm really split on the gas issue. one side indicates, enviornment, stops urban sprawl, stops our dependancy on foreign oil, death to traffic, and that eventually oil will ultimately disappear. maybe we need to ween ourselves now. but another side indicates, not everyone works in the city, public transportation is not available everywhere, not everyone can afford to live in the city, and above all, it's not like our economy can simply switch off from petro just like that. so, i can only speculate on one major factor, probably the most important factor. that humans do not change unless they are economically forced to. but i fear. a tremendous shift will occur. before north america was the centre of manufacturing, now we are the center of "service" and "technology" based industry. i don't know what the new economy will be like. my old high school teacher said that during the 50's and 60's they saw a future where 10 people worked 4 hour days. who knew that it would instead translate to 3 people working 12 hour days.
