After drivers switched their profile photos for those of other drivers in Uber’s system, London’s transportation authority refused to renew the ride-share operator’s license. Passengers were picked up by the wrong driver more than 14,000 times, the authority said, after photo swaps were made in the company’s main system; passengers saw a name that didn’t match up with the photo or the driver who showed up. The authority said that also meant some drivers were uninsured and even unlicensed.

Another issue let suspended or fired drivers create new profiles and keep driving for the service.

Uber vowed to appeal the license denial and said it will keep operating in the meantime. All of its drivers, it said, have been audited, and a facial matching process is in the works. Read the whole story here.
