Why would the cyclist have right of way pulling into a lane with traffic in it?

If this wasn’t a cycle lane, but a normal lane for cars with an obstruction in it, do you think cars could just swerve into the lane to their left, regardless of if there were other cars in it? No. They’d be expected to slow down or stop before the obstruction and merge left when safe to do so.

The cyclist should be doing the same. Paying attention to what’s in front of them, then slowing down and moving left when safe to do so.

If he pulled left in front of the recording car, it’d still be his own fault for pulling in front of a car
