I currently have a courtesy car. I ended up driving very late last night and it was pretty much pitch black (2 hour drive home, motorway).
Anyway, loads of cars kept flashing me and then beeping. I couldn't work out why. But something felt very odd. I couldn't see the rode behind me in my side mirrors. To the left was black. This man drove beside me whilst he was on the fast line and done a hand movement to suggest lights.
I pulled over at the next turn off and came to a side street shortly after. Looked like lights were on '3' to suggest fully on? My own car is automatic lights that adjust so I had forgotten all about this stuff.
Anyway, back on the motorway thinking it was sorted and I still couldn't see well. So more cars beeped. I was frightened that nobody could see me until it was too late so pulled over to the next place and it was this police only thing that went like a turn off but was no entry. I panicked. I couldn't build up speed to enter the motorway again like a hard shoulder. I'd have to reverse and join again like that but there was no space really and it was busy for late at night.
Another car pulled up and all sorts of things went through my head. This woman came to my car and tapped on the window. I rolled it down and she smiled and looked so safe. She told me what to do. The lights came on full beam (it was a bit to the left like the indicator). She told me to keep going and I'll eventually join the M11 again. I looked again. She was gone. Bright blue car gone. Nowhere to be seen. Vanished.
She didn't reverse out and didn't go in front.
Spooky.
