Me too, not because I am some sort of hardman but "getting away" on a bike is a tough ask and I would rather deal with the "human" than that human in 2 tons of car/van frothing at the mouth.
I would also always try and get off my bike before they got close enough to clump me, when similar situations have happened to me in a car and I have tried to ignore it, it nearly always keeps escalating, when my temper bursts they have always backed down or run off. Thank god. I think by ignoring and or running you fuel the bullies ego to overflow.
If the OP is content with outcome no problem, but gobsmacked it never went further.
