I had a situation that was closer than I would like. Approaching a stop sign at a T junction, with a wooded area blocking view. Someone on a bicycle made a sweeping left turn (from my right, to oncoming me) cutting the corner of the junction by a lot. If I had been a second earlier, this could have been a bicycle-to-motorcycle collision, or maybe the cyclist would have had to straighten out ... and at the speed they were going, they would have been into the woods.
