In the US - or large pats of it, anyway - that's the pragmatic approach. In other places, Europe generally for instance, we don't need more cars. We desperately need to reduce numbers, weight, and size of cars, and continue to ramp up genuinely good and cheap public transport.
The US needs that just as much as us, of course, but it's a hell of a job trying to counter 200 years of Rugged Individualism and at least 100 years of intense propaganda 😂
