“Does the GPS in cars use the phone system or they like the TomToms and others that only receive signals from the satellites?”
Technically no need to. But if your car can tie into your cell phone, then yes, it certainly can transmit location data, along with voice data, and perhaps some video data.
Any smart person would cut their antenna cables going to that bump-out in the roof and then short out the coax. But even with that, they’ll be recorded by license plate cameras and entered into databases.
Like it or not, privacy is GONE...because no one bothered to protect it.
The better objective may be to overwhelm the system with false data. Use ghosting apps to "be" where you're not and mirror apps to "be" in multiple places at once. Lend your phone to your spouse to carry around with her. Clone your congress-person's phone and send the clone along with someone to a conservative forum.
We have the toll ID tags for the few toll roads in our area. Pass under the sensor and it charges you.
Although they now use the tags to monitor traffic flow elsewhere. Have sensors located all over the city and suburbs. Of course they say “those sensors do not collect which specific car has gone by - just that A car with a chip went by”. That’s what they say anyway.
A neighbor said the police also have automated license plate scanners that are constantly scanning for warrants, etc. I have no idea how true that is.
“Like it or not, privacy is GONE”
Yep. The martch of technology.
