Earlier quoted context omitted.
Medallions (whether or not they were a good solution), were intended to restrict the number of cars on the road during peak hours, and enforce some uniform regulations on all taxis (pick up people of all races, etc.) Uber's' innovation leads to a fleet that's easier to regulate due to constant monitoring, and pre-booking data. However, when it comes to traffic congestion, their solution is pure demand-side economics:…
Those cars are registered and taxed to the state, county, and city where the driver lives. These aren't scofflaws driving in from out of town- the municipalities are getting at least their fare share from the drivers to maintain the roads.
I assume this was an accident, but it's actually better.
