What Mr. Bo probably didn't notice was that the road the GPS instructed him to turn onto was adjacent and parallel to the RR tracks. I'd hazard a guess that he had the GPS set to a relatively "course" resolution, say 2 miles or more and had he zoomed in to say 1/4 mi resolution or less, would have seen the road and the RR tracks as separate objects.
I use a Magellan 760 to navigate to unknown consignees when I'm out on a run in my Freightliner. It saves a LOT of time but one still needs to use their grey matter...
