Mostly only out of American big cities (at least in the developed world), the point is to fix that. A lot of big cities in Europe and East Asia do fine without being car-centric.
You're right, in my zeal I overstated a bit. But among the richest/most developed nations there are the US & a few similar countries (Canada, Australia, New Zealand) where a lot of people drive cars and on the other hand western europe and the reach east asian countries (Japan, Taiwan, South Korea, Singapore) where mass transit (and in Europe sometimes also bicycles) is the main form of transportation in the large cities.
