> Drivers already pay for the cost in lost time. It's a 'natural' market.
Except it's not: unless you're extraordinarily prescient (or have access to real-time, accurate-to-the-meter traffic data), the driver cannot act as a rational actor because he has imperfect knowledge about the transaction. And that's assuming he'd act like a rational actor anyways -- and anyone who's studied real life instead of theory will tell you that most actors are not rational except, sometimes, in aggregate.
