Consider the MoPac toll lane that&#x27;s supposed to open in a year or so. It&#x27;s priced based on demand to keep the lane free-flowing at all times (barring an accident in the lane itself). You&#x27;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.<p>Demand pricing will make shared rides take off even in low density cities.
