If I would have followed my borrowed nav system that closely on my way back from NC I would have drove off an overpass at about 100 feet in the air. It seems they re-designed the interchange and had not updated the GPS map yet. It was beeping at me telling me to exit left when I was 100 feet off the ground with no exit in sight.
EDIT:
I bet in the US I could have found a lawyer to help me sue Garmin, the construction company, and the map maker had I done it though.
