That doesn't really make any sense: "trap streets" make sense and are used in, say, the base map that you see when viewing a Google map (that is, in the raster data). But why would Google bother putting a trap street into their own (proprietary) street data used for routing? Unless you are saying that Google Maps "directed" you in the sense that you were looking at a printout of a map that included a trap street, not actually a turn-by-turn.

I agree, it doesn't make any sense. But it happened. This was back in '07 or so, so before Google did live turn-by-turn. I had a printout of Google's directions from online.

It led me on a street that's never existed, and that would have had to go either over or through a very substantial hill to actually exist.
