Google maps actually tried to kill me once. I was driving down Hwy 59, to a remote farm I'd never been to before, and for some reason Google Maps thought that there was a break in the highway. Like someone with an eraser just swiped a 1-inch stripe across the highway that was impassable.

I trusted it because I didn't really know where I was going, and it had never let me down before. So I followed its instructions down a series of little farm roads to detour around the "break". Except one of the roads crossed under a raging stream, and was only passable during the dry season. I actually fishtailed a little to stop, because the road was slightly downhill and made of dirt. If I had followed the instructions, I would have died.

Anyway, I submitted a bug report about that highway break, and 5 months later Google wrote back and said my fix had been accepted! How thrilling.
