Stopped in an ASL on the way home yesterday. Car pulled up alongside me, in the ASL, straddling on to the wrong side of the road. Has clearly not stopped properly, he's still slowly rolling forward, and if he decides now to turn left (he isn't indicating that I can see) then I'll be in a pickle. "Oi!" I yelled, "Do you know what you're doing? You know you're in a cycle box? Back off!". Loud enough to be heard through his window, not a scream or anything. Wound his window down, said "Listen, I don't know how things work in Poland, but here we don't..." and then I have no idea what else he might have said. I was pointing and laughing at him too much.
