Transport for London, which oversees the UK capital's transportation system, deemed the ride-hailing giant Uber "not fit and proper" to hold a license, saying it has not done enough to stop unlicensed and uninsured drivers from carrying riders. Transport for London officials say unauthorized drivers were able to upload their own photos to other drivers' accounts, allowing them to pick up passengers posing as the real driver. That happened on at least 14,000 trips all of which were uninsured and some of which were taken by unlicensed drivers, one of whom had their license previously revoked, the transport agency said. Can this be thought of as an adverse selection problem? Explain why or why not.Why is the driver reputation system not a good way to take care of this problem?
