I wonder how easy it is for an unfamiliar pilot to “drive” around and recognise the different features that were discussed. Seems like you are relying on someone understanding the instructions over the radio and navigating the “roads” they might be seeing for the first time. Is this super easy and hard to get wrong? Seems like even some (automated?) traffic lights would be enough to have stopped this but I know nothing about it so would be interested in hearing what it’s actually like.
