Very interesting I will look you up, great outlines posted here, I agree with the fact we can be much more efficient, everybody having 2 cars is too much, it seems that technology in general has made us lazy and we forget that we didn't have it 10 years ago, for instance there were no smartphones that you can use to watch internet videos on, not to mention there were almost no true internet "apps" like we have now.
If we use all the advancements we are getting every day and use them efficiently we can really make a difference :)
