Classic Left Cross
Fortunately, the cyclist was not injured.
Keep in mind, when you are passing a queue, every gap in the adjacent traffic is an opportunity for someone to turn left across your path. It’s very likely the gap is there because a driver in the queue is leaving an opening for crossing/turning driver at a driveway or intersection. You may not be able to see the crossing/turning vehicle, but you can certainly identify the conditions. Passing a queue should not be done any faster than you can react and stop instantly (for me, that’s about 6mph).
If the queue is short, it’s safer to get in line. If it’s long, be aware of the risks and ride accordingly. Or use a different road.

Remember, a screened left cross can happen when you’re controlling a lane, too.
That’s your public safety announcement for today. Carry on.
