I give the occasional arm signal. For example this afternoon, Iâ€™m turning left from a major to a minor road. Thereâ€™s a car waiting to turn left out of the minor road and the only thing heâ€™s waiting for is me. I give the arm signal and thereâ€™s no â€œdid he leave his indicator onâ€ etc grey area, and he pulls out nicely and everybody makes progress. Anybody else use any arm signalsâ€¦ I mean everâ€¦ at all?
