Uber and Lyft may be making San Francisco’s traffic worse

Now, a new study suggests the biggest culprit, from 2010 to 2016, were cars driving for the ride-sharing companies Uber and Lyft, which are both headquartered in San Francisco. The new findings, based on a computer model that simulated the speed of traffic with Uber and Lyft vehicles removed, echo those of another study of New York City. Uber did not respond to a request for comment, but a spokesperson for Lyft said the study—which has the potential to affect transportation policy decisions from San Francisco to New York City—does not adequately account for traffic growth because of tourism or delivery services like Amazon.
