My wife is a Manhattan veteran and does all the driving there. I just hold on for dear life as the frustration starts to mount. However, I still think the best measure of overcrowding is in the London Underground: the Northern Line north of Tooting during morning rush hour. Veteran Japanese professional train packers have quit in tears at the thought of it. Which leads me to think: what would the commute times be like if the entire population of the world did move to Texas?
