I guess it's time for GPS malfunction stories.
Driving across country on a toll way, I encountered a newly built interchange combined with pay booths. Actually it was still under construction, but was operational with attendants in the booths. Two toll roads interchanged, and the signs were confusing. The GPS showed me off a road and in a field, but it was still talking and giving directions.
Somehow I had entered a road system into the Twilight Zone. After 15 minutes of driving, I found myself approaching the same toll booths with the same toll taker on duty. I just paid the toll, and tried my hand again at finding my way, but 15 minutes later, I was going through the same toll station with the same attendant for the third time.
In despair, I asked the attendant for directions to get onto "Interstate Whatever." Apparently, I was not the only one who had been having the problem, because he reached down and pulled out a set of directions that specifically dealt with my problem. No map, but with steps 1-6 for getting to the right road.
But it didn't work, and 15 minutes later, I was at the same toll booth again. It's like 3:00 AM, with few drivers on the road, and I'm frustrated and embarrassed, so what I did was just take the next exit that led off into the woods in a westerly direction, which was more or less the direction I wanted to go, and drove for a half hour without the GPS. I actually turned it off until I figured I was far enough away from the new interchange under construction, and at a point where the GPS would just recalculate from a location that would not involve that interchange. And pretty soon, I was out of the Bermuda Triangle of Interstates, and on my way again.
