No urban designer or transportation expert thinks that cars scale with population. Talking about rural and small cities is the opposite of scaling with population. Car dependent big cities like LA or Houston have hellish traffic.

At least have a cursory look at the link I posted in my last comment. Cars play a huge role in bad land use. This is why they have an enormous effect on housing supply.
