White cab drivers in Cairo are trying to mirror their ride-hailing app rivals Uber and Careem using instant messaging app WhatsApp, Al Masry Al Youm reports. A number of drivers have launched a group on the messaging app dubbed “Taxi Whats,” which works as a more rudimentary version of the ride-hailing apps, allowing clients to request a driver a half hour in advance through the group. An administrator coordinates with available drivers and forwards clients the driver’s picture and license plates numbers.
