There probably aren't a lot of people getting cheated, paying a lot in and getting nothing out, because so many people drive, yes. This is a valid point (although the distribution of infrastructure spending may not match the driving). However, the other trouble with automobile subsidies is they are invisible. An individual can't see the true marginal cost of their use, either direct (road wear) or indirect (sprawl, parking lot oceans).

Behavior would change dramatically if, e.g., you had a GPS tracker logging miles and you paid a monthly road use bill, and parking spots were all metered at their true cost.
