Its mixed is it not { i know on stw we need to pick one side only and argue it to death but bear with me for dissenting] If I had failed to see a cyclist and skidded to a stop just missing them I would have apologised
Had it happened to me, as the cyclist, I think I would have said something
The OP probably over reacted but many of us would have said something to the 2 ton box driver who only just managed to avoid killing/injuring us by driving really poorly.
