and investigators have been doing the activated microphone thing for years.

Using GPS positions to cite you for speeding is not yet possible and is unlikely as several attempts to overturn speeding citations using that data have failed. In one case I recall the father had fitted vehicle tracking to his son's vehicle to stop him speeding. The police cited the son and the tracker showed the boy had not been speeding but the judge upheld the conviction because GPS data was not, he said, accurate enough.

Police like the "freedom" of being able to pull people over on a (false) pretext. Stop light damage, speeding (you were doing 32 mph in a 30 zone) the ever popular "driving erratically" and tyre inspection are all used. All to often they are excuses for the real crimes of "driving whilst young," "driving whilst brown," and the ever popular "you're young, dark skinned, from out of town and driving a better car than me."
