Rules of the road please help

[mtread]

100% green car. Cyclist is perfectly legally overtaking stationary traffic, even if on the wrong side of the road (assuming nothing coming the other way). Green car should only pull out if it is safe to do so. Being flashed by another car means nothing. The green car needs to take account of the bike's stopping distance, not the other way round. Presumably the pushbike is not speeding !
