I played with out early on and tested it on my daily commute. I was pleasantly surprised when 2 out of 3 possibilities matched two of my normal routs almost exactly. The third was OK, but I never went that way because it wasn't as nice as other options.

A also tested other routes, and they were pretty good, though they missed a shortcut on a route that was impassible to cars, but OK for bikes because of a 50 yard pedestrian right of way connecting two roads.

They do accept used input and corrections and have always been responsive when I provided local inside knowledge. I'd like to believe they're still in Beta after all this time because they're waiting for more user info about local factor that they can't gather by driving around those google cars.

I still use Google, to get a sense of what they suggest, then apply my old fashioned map reading skills to get some sense of the lay of land. One thing I DON'T LIKE about google is that it's harder to get a sense of roads than it was on paper Rand Mcnally maps. However, they do have the advantage of street view which can resolve any doubts about what a road may be like.
