Ever wonder how Google gets its traffic information?
Apparently, there are two sources. The first is the Department of Transportation. The second consists of Android users.
You can always check Google Location History to see what sort of data Google has. (Of course, they may always have more than they show.) Seeing the data can be a bit unnerving. Since I’m not really into giving Google more data than they already have to begin with, and I see no reason for Google to know exactly where I spend my time, I decided to turn this feature off.
Turning it off
You can find the setting by running the “Google Settings” app. That’s right, not “Settings”. Once there, select “Location”.
As you can see, I want to treat Google apps like any other vendor’s apps. As an added bonus, it looks like my GPS is on way less often.
