Keep in mind anything a company like Google knows about you, a government official (including law enforcement) also can know about you just by asking. You don't own the information they have on you, and you have no constitutional protections against unreasonable search/seizure. Consider what would happen if your state just decided to issue traffic tickets based on info Google collects from your phone as you're driving along. They probably wouldn't do a blanket "fine every infraction everyone has committed this year" - instead, they could go after people they want to supress. Or maybe they would fine everyone. Some politician wants to fund something, and they get some geofenced data and fine everyone who exceeded the speed limit this year.
