SignalTrace “links devices that regularly travel together, correlating them to license plate.” It is a surveillance product that will sweep up and add all sorts of Bluetooth and other data to license plate readers, linking specific devices—and people—to cars.

+5 for degoogled OS with profiles capability
+3 for Firefox forks like Librewolf or Waterfox with Port Authority and Privacy Badger

A little overkill for most people.
There’s no IMSI tracking through WiFi afaik, only cell service.
Airplane mode, VPN, and messaging apps is pretty good. I believe randomized MAC is the default on Android so no need to modify there. (Though it’s nice to disable that on your home network so you can track yourself.)
Could be overkill, but if you’re out and about your cell data is likely on. Then what? Now, my phone, my laptop, or other devices can utilize it. Unlimited data.
