The only thing that will do that is regulation, either mandating the types of cars we can buy, or taxing the kinds of cars we don't favor.

People in the majority prefer large, powerful cars, given the choice. And those cars already cost a lot, so any strategy of price increases to discourage them will have to be significant. This is why most people in Europe drive small, economical cars. Big cars are heavily taxed, and so is the fuel they use.

I drove smaller cars in Europe simply because bigger cars don't fit in many places. I don't think it has much to do with price.

Small streets mean fewer drivers. That means your overhead demands that you charge more per customer since you have fewer of them.

All that said, smaller roads mean smaller trucks which means more trucks more often which means more tires.
