Google also doesn't know when there's roadwork, and will happily suggest that you take a street that's going to add 15-25 minutes to your journey, but only this weekend. I once had it give me three routes: head down 210th until you're halfway to your destination, then take a right and drive to 220th, then keep going; head down to 220th until you're halfway to your destination, then take a left and drive to 210th, then keep going; or head down to 220th and drive the whole way. My wife, who grew up in the area, said 'that's stupid', drove down 210th the whole way, and got us there faster than we would have otherwise (because we weren't taking any left turns on busy routes the whole way).
