What in the hell was going on there? I mean, I get GP's point about aggressive cyclists. I noticed them in Berlin especially (straight, wide roads on flat terrain), but even then people will usually try to brake before they run into you. This kind of damage sounds insane. Was the cyclist hitting him at full-speed? If so, how???
You have main road, then a curb followed by a bicycle lane followed by a buss stop with a pedestrian sidewalk behind it.
If you want to get to the buss you need to cross the cycle-lane.
If the cyclist is careless and speeding, and you maybe are not paying enough attention, bad stuff can and do happen.
Just the other week a guy got hit in the arm by a slow riding bike while waiting, which made him so pissed he grabbed the bike rider by the arm and kind of threw him to the ground.
People had to separate them from fist fighting.
