New York City is looking at numerical limits on ride share vehicles because of the congestion that they caused.

If this sounds familiar, it is exactly the same justification that was used for the originally taxi medallion systems, that an unlimited number of hacks on the road would result in massive congestion issues:

New York City officials are moving to cap the number of vehicles driving for Uber and other ride-hailing services as part of an aggressive move to address mounting concerns that their explosive growth has led to worsening congestion and low driver wages.

The legislation being considered by the City Council would make New York the first major American city to set a limit on ride-hailing vehicles, which in a relatively short period of time have transformed the transportation networks in cities across the world. Mayor Bill de Blasio, while stopping short of fully endorsing the proposal, suggested that the time had come to rein in the industry.

The proposal supported by the City Council speaker, Corey Johnson, would halt the issuance of new for-hire vehicle licenses, except for vehicles that are wheelchair accessible, while the city conducts a yearlong study of the industry.

It is the second attempt by New York City — Uber’s largest United States market — to cap the company’s vehicles after a failed effort by Mr. de Blasio in 2015. Since then, the number of for-hire vehicles in the city has surged, rising to more than 100,000 vehicles, from about 63,000 in 2015, according to the city.

 Truth be told, they really don’t need another study, there already has been a study done:

The explosive growth of Uber and Lyft has created a new traffic problem for major U.S. cities and ride-sharing options such as UberPool and Lyft Line are exacerbating the issue by appealing directly to customers who would otherwise have taken transit, walked, biked or not used a ride-hailing service at all, according to a new study.

The report by Bruce Schaller, author of the influential study “Unsustainable?” which found ride-hailing services were making traffic congestion in New York City worse, constructs a detailed profile of the typical ride-hail user and issues a stark warning to cities: Make efforts to counter the growth of ride-hailing services, or surrender city streets to fleets of private cars, creating a more hostile environment for pedestrians and cyclists and ultimately make urban cores less desirable places to live.

………

Schaller found that while options such as UberX add 2.8 new vehicle miles for each mile of personal driving they eliminate, the inclusion of options such as UberPool and Lyft Line adds to traffic at only a marginally lower rate: 2.6 new miles for every mile of personal driving reduced.

………

“Shared rides add to traffic because most users switch from non-auto modes,” the report says. “In addition, there is added mileage between trips as drivers wait for the next dispatch and then drive to a pickup location. Finally, even in a shared ride, some of the trip involves just one passenger (e.g., between the first and second pickup).”

Ride sharing runs into the Tragedy of the Commons:  Roads are a publicly held resource, and individual actors attempting to maximize their own personal benefit are damaging that resource.

Unfortunately, privatizing and/or abusing the commons seems to be America’s primary growth industry these days.
