Thanks, I've just checked it... Well it is frightening, all search and videos activities are recorded, almost as an online diary. On a positive note one can use it as a memo for recalling what you've been doing on a particular day. We are way beyond big brother...
I just took a look. There'a lot of information recorded. For one of my Google acounts there's more than 10 years of data. However, the only thing that gets recorded in that account these days is some of the videos I watch on YouTube. I have one browser I use solely for watcnig YouTube. In my other browsers I'm never logged in to a Google acount. I have recently started following some channels on YouTube. If I ever decide to follow a channel I launch the other browser to follow it. I never log out of Google on the second browser. I have another account I use on my phone and tablet. It seems to be mostly record the apps I launch.
Yeah, I'm expecting sometime in the not too distant future automobiles will be self-reporting, so when someone is speeding, a blackbox GPS-type unit in the vehicle will generate and send a report via satellite or cellular, and a speeding ticket will be promptly mailed to the owner of the vehicle. Your driving history, where you've been and speeds and so forth will be kept in a database and recalled by authorities if needed. Dash cams already mandatory in Russia will be part of the "package" as well.
