Was driving from SF to Big Sur some time back. Google totally tried to take me off road from HW 1 [turn right. turn right now], and then calmly stated "There is no route to your destination".
Google Maps is frequently broken around the thinly-populated Seattle metro area. I've filed bug after bug, to no avail; in the end, I stopped using it altogether. It cannot handle the I90 express lanes in either direction; getting directions to somewhere on Mercer Island from Seattle when you're on the express lanes eastbound gets a route to Bellevue, turn around, and come back. No, that's OK, I'll take one of the Mercer Island exits, thank you.
Furthermore, the transit integration is so broken as to be useless. Asking for a route from Kirkland to the Seattle federal building gives you a bus route to downtown Kirkland (the post office, actually). The POIs in that area are AFU.
