Motorcycles in your bus lane

I'm confused about this. Do you really object to a left turning car (or motorbike) hugging the left side of the road at lights? Why? That's what they are taught to do, specifically in order that a cyclist doesn't take the inside and then crash into a left-turning car.

I always do that. I absolutely want you to pass me on the right if I'm about to turn left, because then I know you're safe and I know I'm safe.

I object because this often happens at red lights. As in the light is red but some car driver sees fit to overtake me, then hugs the curb so close that I have to take the high side. You are right in one sense, if a vehicle is specifically turning left then it's OK that they would not provide me with space on the left. Often though they are going straight and yet do the same thing.

Personally, I am very careful and would never pass on the left a vehicle that was actually signalling to turn left. However, a lot of drivers that are planning to go straight simply overtake and then close the gaps for cyclists. It even happens at ped crossings when there is no opportunity to turn. The car simply comes in front and then stops, blocking my path.
