I can't remember enabling it. That isn't to say that I didn't enable it, but I can't remember actively saying "yes, please track my every move". I don't think that I would have said yes to that if I was aware of exactly what I was agreeing to. It appears that the complete tracking of my life started when I bought a nexus 4 - I'd imagine that I clicked through a box without really understanding what it was saying.
I will categorically say that I've never been reminded that this is enabled. Until today, when I realised that a complete log of every movement I made in the last 8 months was available, I had no idea that this level of information was viewable to anyone logged into my google account (I'd imagine that something similar has always been available to law enforcement regardless of opt-in status).
I'm not arguing that it shouldn't exist (I now understand why google now always uses my exact route when estimating commute times, and I did have a nice nostalgic trawl through this year's activities) but I do think that transparency that it does exist could be greater.
