Conventional taxis in New York City are soon to be replaced by vehicles with sliding doors.

One concern is that passengers will fling such a door open and step into the path of eg another car or a bike.

Today’s invention is a sliding door which has a hinged, L-section hatch section overhead.

When the vehicle stops, the hatch opens but the door will not slide until both of the (blue) rooftop cameras have registered that the passenger has looked both ways.
