I don't have it backwards, you're just not following what I'm saying. I agree that denser housing and construction in general is far more efficient. However...

I'm not talking about constructing a town from scratch. I'm talking about an existing town. Adding the infrastructure for high density housing to a town that wasn't originally designed for it is very expensive.

Current "trend" is medium density housing, with smaller roads. Most of US is 9+ months out of the year a walkable climate.

Putting down a small self driving street car for short trips removes a lot of road congestion in town. And if you just place navigation tags into the pavement - you avoid the need for expensive AI based nav system.
