5G is nothing but marketing wank. Carriers aren't deploying some new sci-fi technology, they are just incrementally upgrading their networks to a more recent (and backwards compatible) revision of the LTE standard.

5G is a generation of cellular network tech that allows higeher frequency and more spread out (oversimplifying a bit) cell "towers". Even if you don't use 5G (or any tech at all) it can be used to track your movement with good precision.

An optional part of the new LTE revision is support for millimeter wave radios. These radios have very short range and so you would need a lot of them, more like WiFi hotspots than cell towers. I guess that means that the carrier could geolocate you better, but only if you have a supported device and are very near a millimeter wave AP.

The fact that this software is named "Big Brother" is pretty on point.

Also pretty much every car in a few years will be connected all time, so someone somewhere will always have the means to monitor its position, visited places, conversations, etc. There's no solution; in just a couple decades we transitioned from local private unconnected CCTV (shops, malls, etc.) to pervasive government surveillance in cities, and we adapted to it; from this to drones with cameras flying and connected 24/7 it's just a matter of time. And we'll also adapt to that. In due time it is entirely possible that each one of us will have a personal governmental drone constantly following us to prevent crime, though actually in our pocket we already carry one which cost nothing to governments.

I know what you say is possible but that's my point. That's why we have laws. The government and corporations/feudals use to be able to do a lot worse but now we have laws and enforcement of those laws.
