You seem very much in favour of cars, but also imagining that cities without cars would look much like cities with cars. Huge amounts of land are given over to roads and parking. Get rid of these and you have much denser cities without decreasing usable space per inhabitant.

I assume you're talking about US cities. Because IMHO most European cities are already far too dense. You can hardly see the sky.

All cities with cars, and no, they aren't.

But if you make cities even densier, you'll have to restrict their height. People on the first floor still want sunlight for a reasonable time :) Meanwhile wide streets allow tall buildings..
