Frankly, I would not even stop at Maps. Since a year or so Google makes so intensely use of all sort of metadata (my browsing interests in the future, the places if have visited, my contacts on G+) that the internet has become a small world for me. I find myself increasingly using duckduckgo just because of this. Heck, as I use the public DNS servers of google, even deleting Cookies or using browser porn mode doesn't help much.
It's an example that overly smartness actually degrades the experience for me rather than being and improvement.
