Google Maps has arguably gotten worse. Many times businesses that don't pay to be listed either won't show up on the map/in search or at best show up basically last. I also live in the Bay Area and sometimes I feel like the GPS routes it chooses are to avoid certain areas even though they'd surely be quicker. For instance sometimes it insists on me taking 101 around Palo Alto/MTV when traffic is just yellowish but other routes are totally clear, and 101 ends up becoming nearly stop and go when the other routes are basically still clear.

I will say google maps is superb for traveling in Japan, though.
