Most modern cars phone home on lte/4g/5g. Police could auto-ticker speeders if they wanted to today. Probably don't want people to know how ubiquitous the tracking already is though.
I am not sure why you are being downvoted. The potential for abuse is clearly in place. It did not happen in our timeline yet, because it would likely cause an uproar, but to me writing was on the wall, when, way back when, Elon sent an update to a Tesla during a disaster to change a battery behavior.
