> In San Francisco, the mayor, London Breed, instituted a 15 percent cap on commission fees, a move that prompted Uber to suspend deliveries to Treasure Island, which sits in the bay separating San Francisco and nearby Oakland and is home to a number of low-income residents.<p>> In Jersey City, Uber reacted with a $3 surcharge to consumers after the city’s mayor imposed a 10 percent commission cap. In Chicago, an order due to come into force later this month will not force a cap but instead demand transparency on fees so customers have a clear picture of how much of their payment goes to restaurants.<p>> New York City is poised to move next: a bill seeking to impose a 20 percent cap is on the table this week, supported by the mayor, Bill de Blasio, and gaining momentum following news of the possible Grubhub deal.<p>It will be interesting to see how all of these different approaches play out. Are the caps governed by the restaurant location or the customer location? Or either/both?<p>Will Uber push back at all? It seems some sort of regulation in this space is inevitable so at a certain point I expect Uber will start to lobby for uniformity rather than a patchwork of rules that differ by zip code. I can imagine the cost of compliance quickly getting out of hand.
