Comment A very similar thing happened to me (Score 1) 699
Google gave me walking (actually bicycling but never mind) directions which all but crossed a 6-lane highway. Since said highway was surrounded by a tall fence, a trench and a shrubbery, I didn't apply for a Darwin award, but instead BFS'ed for a few minutes until I found a proper crossing.
As a coder, I know it's terribly difficult to write a proper pathing algorithm! I guess since I know that I'm more forgiving (just as I'm less likely to rage at buggy games).
