It is not subject to traffic. People don&#x27;t have infinite money. There is a price at which few enough people are willing to pay that traffic flows freely. That is the price that will be set. People who don&#x27;t have a choice of when to travel will share a ride to split the cost.<p>Yes, the driver will need to be paid as well, but people often run carpools that only charge for the price of gas. The prevailing rate for a ride will be low because there are plenty of people heading in the same direction who just want to defray their costs. Regardless, the mechanics of congestion pricing guarantee that people will use alternatives to driving. The congestion price will go up until people start choosing to share rides, take transit, or do something else.<p>Congestion pricing works. It&#x27;s not an untested idea. It just isn&#x27;t widely used. It should be, because it eliminates traffic. Ride hailing apps give even cities without great transit a great alternative to driving alone, which makes congestion pricing a universal solution to traffic.
