For the most part, I thought it was a good start. Yeah it wasn't great, but for my route to work it did offer three options on the left. One of which I wouldn't use due to high traffic, but the others were pretty good. Not the routes I take, but still pretty good. Looking at the map data, I also see that their Illinois Prairie Path data is only partial. I know that there is a path route that will take me from my house to my parents (about 40 miles away), but Google doesn't seem to have any of the Cook County paths in their system yet.

So definitely just a start.
