Regarding roundabouts: Once of the best pieces of advice I've received is that you should assume you're entering the roundabout at 6 o'clock and the navigator should tell you to exit at 12, 3, 9, etc. While it's sort of counterintuitive to think of entering at 6, it makes complete sense once you're doing it. (Of course, this assumes you're of the generations that can read analog clocks.)

Which navigator uses that terminology, and specific to Morocco or in general?
IME Google Directions and possibly Waze identify roundabout exits as 1st, 2nd, and 3d. Occasionally a simple intersection may be incorrectly identified as a roundabout -- in which case those "exits" would respectively mean right turn, straight, and left turn.

I was referring to human navigators! (It was actually advice I originally received before driving in Ireland.)
