I couldn't be bothered with agro so I had quite a reasonable conversation with him in the end, but just asked him to think if signalling at the last minute then turning across a cyclist before they even have time to brake like that is really reasonable, given if took all my skill to avoid hitting the side of his car.

It's always quite fustrating how drivers somehow don't register cyclists as a vulnerable road user, and somehow treat them as they'd treat a car as if nothing bad going to happen to the cyclists.
