So the rich a$$holes get the safe roads, while the cash poor get the risky ones. Yup that’s just the right outcome.
Roads are somewhat special because their construction is often impractical without eminent domain, and because many roads are used so far below capacity 99.9% of the time that the marginal cost per vehicle mile is essentially nil, rendering market pricing concepts irrelevant. That having been said, in general the effect of using free markets to allocate resources is that the rich get better stuff but pay a lot more for it. What's wrong with that?
