Ian Adams, who studies sharing economy rules for the libertarian R Street Institute think tank, is skeptical that rideshare-only congestion regulations would be effective at speeding up traffic. But he did praise the city for keeping the license cap to only one year, to then be reevaluated after study.

“I think that expresses some level of skepticism they have internally about this approach,” he said, regarding the city council. “It may harm their own constituents and I think they’re aware of that as well, and they’re reluctant to do something that will irretrievably destroy the system. That said, I think there’s a reason we haven’t seen other large cities go this way.”
