I understand what he's suggesting and I do agree that we need to fix up our town planning.
And that's why my point wasn't that he's wrong about his suggestions, just that, again, it's "much easier said than done."
For the foreseeable future, owning a car is the only reasonable way of getting around many parts of the U.S.
How long do you think it would take to fix up even half of the cities in the U.S?
How can we fast track it and what are reasonable expectations since there will be pushback from people?
In a way we would need some sort of Haussmannization to occur and that will not go well in the U.S.
This may be true in Europe and in cities for those who both live and work in the city. But for the vast majority in the U.S. It's practically required to have a car if you want to work.
