Uber on Wednesday stepped up its battle with New York Mayor Bill de Blasio, calling his plan to restrict ridesharing growth a sign of "contribution politics."
De Blasio cited such issues as increased congestion and pollution for his proposals, which would include a traffic study to be completed in the next year showing the impact of ridesharing companies. In the meantime, he wants to limit growth of for-hire vehicle companies to 1 percent.
The New York City Council is expected to consider the mayor's proposal this week.
"I think congestion is no doubt a problem in this city," Uber NYC General Manager Josh Mohrer said Wednesday. "[But] putting an artificial cap on supply to study congestion ... doesn't make any sense."

San Francisco-based Uber, with an estimated valuation of near $50 billion, has said the bill would cost New York nearly 10,000 jobs.
The company also claimed that de Blasio is trying to stifle free enterprise and innovation because he's in the back pocket of the Yellow cab industry.
"This cap ... isn't about progressive politics. This is about contribution politics. This has nothing to do with [de Blasio's] politics," asserted Mohrer, who said as a Democrat he supported the mayor during the election.
The mayor's office did not immediately respond to a CNBC request for comment, but it has dismissed those allegations—saying New York City is not alone in its concern about Uber, citing unrest and litigation in London and Paris, as well as the state of California.
