>>870494This can only happen as a result of both the cyclist and the cager making a mistake.
The cager ought to keep to the right whenever he can, other than when he's overtaking or turning. He isn't turning, and is not allowed to overtake at an intersection, so it's established that he has no business being on the left lane, even though it's not flat out illegal.
The cyclist ought to take shortest turn possible, which would be from the left lane on the vertical street to the left lane on the horizontal street (unless the horizontal street is two-way).
Being the cyclist, you should make sure to hold up your end of the bargain. It should not go against the legal commitment to ride as far to the right as safely practicable, because you put youself at considerable risk by being in a lane where you can get t-boned like that.
Logically, it follows:
>When turning right, do it from the rightmost lane, as far to the right as possible without running the risk of getting doored or boxed in by a parked car..>When going straight through an intersection, go through the rightmost lane from which it's not allowed to turn right. If no such lane exists, go from the leftmost lane through which you can go straight.>When turning left, do it from the leftmost lane, while riding towards the center or left of center so as to reduce the risk of cars trying to overtake you and smashing you into the lane to your right.Practically, I guess you'd have to weigh this against the risk of incurring all those lane changes before and after the turn. I personally ride this way only when the roads aren't too crowded.
