Is it OK for rear fog lights to go off when the ignition is turned off?....

Who cares? I never ever use mine. They look like brake lights. So
when you brake, the person behind doesn't know and slams into you. A
very dangerous invention. Tail lights are enough for the following car
to see you. If they aren't, they're driving too fast for the
conditions and it's their problem.
Which bit of "fog" do you not understand?
