were you not also taught it is a really stupid idea to overtake when approaching a junction on the right? I would say this is 90% the cyclicts fault, OK the car should have indicated and checked his mirror but tbhe cyclist should have anticipated someone might be tuning right and more to the point someone might pull out from the junction. It was fairly obvious the car was thinking of turning right. Cyclists and motor bikes may be allowed to pass stationary traffic on the right doesn't mean they should do so regardless of what's happening.
Exactly. And you can see where the car began the turn long before the biker began to react. You cannot assume that they will notice your approach and cease their maneuver because you are coming.
