Consider the MoPac toll lane that's supposed to open in a year or so. It's priced based on demand to keep the lane free-flowing at all times (barring an accident in the lane itself). You'll be able to shave significant time off your commute by paying extra, or you can pay less by sharing a ride with other people. Demand pricing will make shared rides take off even in low density cities.
