It may be location dependent. For example, it doesn't know that I can bike across the street by my place, because there's a tram line down the middle. So it insists I go all the way to the end to turn around. It'll often also tell me to go a way that involves a left turn across effectively two lots of traffic, which is a nuisance when it's busy. Usually I use its routing as advisory, and figure out my own way based on it.
