Google, if I recall correctly, was sued by a woman when their maps told her to take a pedestrian route that didn't have sidewalks and she was hit by a car.
Ok. I just can't resist this anymore. Who, in the bloody hell, is so stupid that they follow their stupid GPS device around like a damn lemming - so the extent that they walk in the middle of the damn street and get their ass plastered by oncoming traffic? What a really top-notch example of natural selection - follow that up with the fact that she sued Google for her own stupidity, and I'm having real trouble feeling any sympathy.
Come on, people - GPS is a tool to help you get your general bearings in unknown territory; always has been, always will be. It won't ever be perfect and it doesn't have to be. Computers cannot (and should not) think for you.
To thine own self be true. (If not that, at least make some money.)
