Google Maps has complied a positively bonkers amount of data. That includes not just mountains of imagery, from Street View to satellites, but databases storing information about all these streets themselves: tolls, one-way status, and more. And while all of that info adds up to making Google Maps as useful as it is, that's also an overwhelming amount of info to have to keep up to date. Google is now trying out a new approach towards keeping some of that info current, although one that's not going to be without a few privacy concerns.
