Transport for London (TfL) has declined to renew Uber's operating license for that reason:
Uber has lost its licence to operate private hire vehicles in London after authorities found that more than 14,000 trips were taken with more than 40 drivers who had faked their identity on the Uber app.
Transport for London announced the decision not to renew the ride-hailing firm’s licence at the end of a two-month probationary extension granted in September. Uber was told then it needed to address issues with checks on drivers, insurance and safety, but has failed to satisfy the capital’s transport authorities.
TfL said on Monday it had identified a “pattern of failures” by Uber, including several breaches that placed passengers and their safety at risk.
Steve McNamara, the general secretary of the Licensed Taxi Drivers Association, which represents London black-cab drivers, said: “It’s all about public safety and the mayor has taken the right decision.
“As far as we’re concerned Uber’s business model is essentially unregulatable. It is based on everyone doing what they want and flooding London with vehicles. Uber cannot guarantee that the cars are properly insured, or that the person driving the car is the one that is supposed to be driving, as recent incidents show.”
I expect Uber will work something out with TfL, eventually. For now, they'll continue to operate while appealing the ruling.
