I have heard about people being blamed after flashing lights to let someone out so I don't do it. Many do though and many don't know what to do when you wait for them to pull out but you haven't flashed.

Lets be sensible about it though, if I did flash to say I was letting you out it should still be your responsibility to make sure your movement is safe. The judge who let it go the other way wants sacking!!
