Self-driving cars decrease the internal costs of driving (allowing you to do it without having to pay attention) while keeping the external costs (congestion, danger, pollution, noise, etc) basically the same. So we'll end up with more driving, with society at large bearing the cost.
Locking this future in for good because of "present infrastructure" would be short-sighted.
