FWIW, TfL doesn't call them drivers anyway, the title is "train operator". I believe this is because their duties combine those that would traditionally belong to both a driver and a guard. Although the regime of working without guards is called "driver only operation", so what's going on there. The crew on the DLR were originally called "train captains", which i think is an excellent name, and should be brought back.
