If it doesn't come up in the list, it won't know it anyways.
I kind of like that I don't have to type the whole thing out... for me, I usually pick the city, then street, then number, and haven't had any problems. It autocompletes it when it has narrowed down the possibilities.
Well, other than freezing halfway to my destination. Or trying to get me to make left turns across medians.
My real issue is that the pedestrian paths are all displayed on the map, in the same colour and thickness as roads. Very handy in a car...
