In my experience, Google Maps too often sends me down dangerous streets - busy, wide, arterials with fast moving automobiles.
Though I do know some people who prefer them because they can be a little faster. Not worth it for me. I'd much rather go a little out of my way for a comfortable safe ride.

Most of us would take a hill with a protected bike lane over a flat 45mph.
