I had the experience you fear in Germany. The gps directed me into a pedestrian area in the old part of the city. I drove quite a ways before the pedestrians suddenly closed around me and I was unable to move. It was technically legal, but pedestrians have the right of way and the speed limit is 5 km/h. It was very stressful at first, but eventually I resigned myself to the situation. I had to slowly execute a 180 degree turn, moving a little bit at a time, waiting for gaps in the foot traffic. It was quite crowded and no one moved out of my way. One guy chuckled and shook his head sympathetically as he walked by.
