This is the cockpit of a yellow cab which I took a ride to go to the international airport. The upper color display shows the engine and motor status of the hybrid system. The power source changes automatically between a fuel engine and an electric motor at a dizzy speed. It is interesting to watch the change but it is useless because the system is hundred percent automatic and the driver has nothing to do to control the system. I think it is even dangerous because it has a possibility to distract the driver's attention. The lower monochrome display is a dispatching system which is much more useful. The drivers can receive a text message from the center to pick up passengers. They used to use radio calls but verbal communication is redundant and ambiguous. I wish someday the aviation radio call is replaced to this kind of text based system.
