When did using a signal light in your car for turns and lane changes become optional? I have had so many near misses lately that I've just about given up driving. And don't get me started about the people who sit through a whole light without signalling and then either turn still without signalling or pull forward a bit and start to signal. Mrs. Idjster is more of a pedestrian and it is one of her major beefs too. So, when did it become optional?
