Uber faced a blow on Monday when London regulators refused to renew the ride-hailing company’s operating permit because of safety concerns. The biggest issue lawmakers cited was drivers using false identities as they ferried unsuspecting passengers.At least 14,000 trips were made by unauthorized drivers, according to city regulator Transport for London. The way it worked is this: A number of drivers would share one account, and whenever one of them went out to drive, they’d upload their own photo to fool passengers. The unauthorized drivers were able to pose as vetted, licensed and insured, when often they weren’t.
