Bloomberg Businessweek blurb on global traffic (image blow-up below).
The numbers suggest a profound shifting of woes from Old Core to New.
The US adds 2% more cars from 2003 to 2007, while China adds 113%, for example, so the traffic-suffering indices presented here show America's worst case, NYC, coming nowhere near the complaint level of your average New Core capital, whose woes are only going to get dramatically worse in coming years.
