Re: Nothing anywhere proves Googles data is concise or accurate.
I checked my location tracking thing one time after an email from Google invited me to have a look. I saw one day in particular I'd been at a motorsport event near the coast, I'd been in the same place all day. Except, according to Google, about an hour in the afternoon, when I jumped about 50 miles out to sea and back again. I must have not been paying attention because I definitely don't remember doing that
