Johana Bhuiyan, writing for Recode: Transport for London, the taxi regulating service in London, announced today that it would not be renewing Uber's license to operate because of concerns over the company's "lack of corporate responsibility" in relation to public safety issues. The ride-hail company, which launched in London in 2012, is appealing the TfL's decision and will be allowed to continue to operate until a court makes a decision on that appeal. That process could take months. London is a significant market for Uber: The company says there are 40,000 drivers and 3.5 million riders on its platform in London. And like New York City, it is one of the most regulated markets where Uber operates. Unlike most markets across the U.S., Uber drivers in London and New York City are required to participate in government administered background checks.
