Careem strikes a partnership with Dubai to manage white taxis: Ride-hailing company Careem is launching a company with Dubai’s Road and Transport Authority (RTA) that will manage the e-hailing systems and online payment for all of the emirate’s 11,000 white taxis, FT reported. The agreement will be the world’s first partnership between a government regulator and a private ride-hailing app. Careem will have a 49 percent stake in the joint venture. The service is expected to launch in April 2019. White taxis will still be able to pick people off the streets, while Dubai’s ride-hailing apps will continue to operate as normal.
