Happened to me in Death Valley, in the very hot middle of nowhere. I came from a dust road and did not fully stop on the stop sign for the main road through the valley, I had only slowed down and then made the turn. Out of nowhere there were park ranger lights behind me. I still don't know if they were cloaked or if they teleported behind me, I don't know how I could possibly have overlooked them. Everything flat and nothing anywhere, suddenly they are there. I don't remember if I had to pay or if it was just a warning.
