It was a car pool lane (but not at the time, it was just a standard right lane) but partly bicycle. Rolled forward a bit to let him through, usually do to avoid people honkingme, and then promptly followed by a cop stopping him. Not sure what happened after but lights did go on.

I guess I kinda set the guy into the trap...

Bonus clip: I can’t tell if this is a kit or the real deal.
