The hero photo for the article shows a camera over a road that likely is likely running number plate recognition software...
Honestly I'd be more worried about where that data is going than the tracking software in your car. They've got the most critical information (where did you drive and when), and they've got it for every car instead of just Honda drivers.
This needs to be fixed with legislation, and it needs to be fixed actively. For example by getting rid of number plates entirely and replacing them with something like the transponders used in aircrafts and ships, but with an encrypted rolling code that only shares your data when authorised to do so (by the owner of the vehicle).
Apple "Find My" works like that... your location is encrypted, and it's uploaded without any identifying information. When the user brings up a map looking for their keys, that's the only time encryption keys are handed over allowing the already stored information to be accessed. The car version of that could be police asking you at every traffic stop to hit a button on your dashboard that unlocks your registration/insurance details so they can run a quick check against their outstanding warrant/etc database.
