This caught me out recently when I was comparing the differences between google and OSM nearby. I noticed a few small towns nearby that were much bigger on google than on OSM, so I started looking for bing imagery for the area, which was very poor (cant even pick the highway into the town). I then decided to compare google satellite to google map data, and noticed more than half the roads in google data simply didnt exist, and quite a lot that did exist were the wrong shape/length or had incorrect junctions.
