Wait really? I feel like this was happening in the 90s. Now every car has a full gps spy system integrated to the point I barely trust that my conversation is private in a modern vehicle. But I guess if you think it's just your car company, Android, Apple, roadside assistance, the local police, and probably the music you're playing that can pin your location you're probably ok.
Literally all of these can be avoided except the external apparati like the Flock cameras, which is why they're such a big deal.
Getting tracked by your map application or OS platform can be countered by using an open source ROM and a local map provider like OpenStreetMap. Gtting tracked by the car itself can oftentimes be prevented by unplugging the telematics unit (or its antennas) or bypassing it with special cables. But there's nothing you can legally do to protect against the Flock cameras, without ignoring the law entirely and going around town with an angle grinder.
