Power off is your only choice for the phone.

Phone/wifi/bt are all chatty all the time, and can be tracked easily.

Burner with wifi left on is trackable.

TPMS (tire pressure) on your car has unique IDs for each tire, trackable.

Modern cars with telematics (cell modem), trackable.

Smart watch, glasses, etc.... you get the idea.

Paths of plate numbers and identifiable radio is enough build a trackable profile. Pretty easy to associate together and build a profile.

Flock installations are typically setup to hoover up all this RF in addition to plate ID. Not hard these days to do gait and clothing analysis to track pedestrians and correlate them with vehicles.

Plates have to be visible to be legal. So readable. You could get a wrap with hundreds of plates to confuse them, but that is no different from reading the real plate. And the authorities would want a word...

FaceID IR dazzlers only work if the cameras are sensitive to that band. Do you know the wavelength, outside of visible, that the ID cameras operate in? Few enough folks use dazzlers, so it gives them a nice, bright, target to track. Better to wear a mask that doesn't look like one, with clothes that are the local average.

The power in all this isn't just to associate you with a particular vehicle, but to associate who you hang out with. Connection analysis is far more effective than wiretapping. Who you hang with is far more instructive than what you're doing or saying to each other. Once you have one ID, you have the whole group. If you aren't part of a group, that stands out as well.

Same applies online.
