This morning at a T-intersection, with me turning right out of the stem of the T (we drive/ride on the left here), I was required to give way to a car approaching from my left and indicating to turn onto the street I was on, as normally we would cross paths. He slowed down as if to let me go, then turned on the wrong side of the road. Luckily no-one else was coming, but I'm not sure he could see that.
