One-armed cyclist done for not having two handbrakes

When I cycled in Berlin I thought it was better than Amsterdam, cars will overtake on your left then wait to turn right, they stop to let cyclists past. Astonishing courtesy. That said one Berliner cyclist bawled me out, I have literally no idea what I was supposed to have done wrong but this German bloke shouted stuff at me in Berlin talk as I stared at him.

Happened to me in Hamburg as well. I think I dared to step into the cycle lane, despite it not being clear exactly where it was.
