"but that creates housing shortages and limits the usefulness of public transport."
The only people who don't like low density are the poor, and this is why most of America is car culture, and owns their own houses. "Housing shortages" is another way of saying that existing home owners are earning strong equity.
Yeah, I do want no traffic and lots of parking, so low density please!
And oil shortage is another way of saying that existing oil owners are earning strong income. Why is either of those things the desired state? (Other than self-interest, if you happen to be sitting on a stockpile of oil.)
Yes. Which is why it's so much cheaper to live in Manhattan than in the suburbs.
High density urban housing, coupled with public transportation, would reduce traffic by removing cars from roads and the distance commuted. I like low density too, but not car culture.
That makes no sense. The most expensive property in the world is in high density cities.
Personally I want no traffic but also little parking. Car infrastructure is a general blight on public spaces.
