Eish George, sorry to hear about the misfortune.
Did you come out of it alright though?
From the pics you posted it seems that there was enough space, where the white line ended to turn.
Now I believe it's the biker's fault, but it pissed me off badly that people don't know the size of their cars and can't take a corner without crossing lines.
Case in point, at the end of my road is a T-junction. Coming into my road from the T-junction is a solid line both from the road turning in, and well as the road turning into.
Every day I need to perform evasive tactics because idiots can't drive properly, and run over the turning in line and the "corner" line of the road turned into, basically "cutting" blind corner and completely going over into the oncoming lane, where it would be a 100% collision for the oncoming traffic as there isn't enough space.
And it's a pretty wide road as well.
The day I win the lotto I will purposely ram into every car that cuts that corner, because it's just plain bad driving on their part.
Maybe I need to illustrate this, as it doesn't quite make sense.
