If I'm out for a frisky drive on one of the fantastic back roads in my area, I power off my phone. Sometimes I turn it off just because. I'm not important enough to have it on all the time. 99% of the time I use my phone it's from home. If I'm in the car or riding my bike it's usually powered off. There is zero chance of me allowing location services just to get a discounted meal at McDonalds.

Edit: Also too, besides turning off location services at the "global level", turn off location services at the app level as well. At one time that was one of those gotchas that our tech overseers exploited.
And lastly, I worked in the tech industry. My last big project before retiring was a REAL TIME phone call tracking system for a southern hemisphere western ally. In the eyes of most I think this country is viewed in high regard. NOT! This was a MASSIVE mainframe installation that in theory could literally track and link together every phone number on the planet. Those of us who worked on that project had uneasy feelings about it because the spying this government did on their own citizens overflowed into the entire world. If people knew what was taking place behind the curtains there would be social unrest. You have absolutely NO IDEA!
