Will be a nice feature once they work out all the kinks.
Ought to be capable of having 180-degree visible turn signals mounted to the side-view mirror assemblies, radar/lidar sensors to know when fast-approaching vehicles or others are in the "danger zone," and ought to be able to loudly and clearly inform a driver/passenger that there's an apparent extreme risks of opening the door right then. Won't be perfect, probably, but it's better than the "wing-it" method most folks employ now.
My own car's about ten years old, and on the sides it's only got the proximity warning lights (for the driver) associated with the side-view mirrors (blind spot monitoring). No turn-signal lighting on the mirrors, and certainly no rear-facing blind spot monitoring as would be necessary for a bike lane. Hopefully it'll come, at some point.
