>Couple of months ago I tried my GPS for real, in Belgrade. Went to see a man about a horse, well, a scooter actually, and the gadget led me the shortest and best way there, sidestreets and no big congestions to wade through, and then to yet another end of the city, again without a problem. Net result, been there, done what I went for, and don't ask me to find the way again - I have no idea where I was. Tetracing? No way.

in late 2010 and early 2011 I was about every second week in former east-germany. More than half a dozen times I would have totalled the car if following GPS info blindly - from being led to drive into a wall or a house to driving into the forest. Usually no problem, but if you are going a bit fast at night you ARE surprized if a wall appears in the road said to go on for 2km...
