Most modern phones. Samsung and Apple use address randomization for WiFi. There are tricks through like announcing common WiFi router names. Starbucks. Netgear etc then looking at traffic.

Also your car has wifi and bt. Which prolly doesn’t do that.

If you wanted to position it you shouldn’t get an adr and park nearby. Also I wouldn’t recommend a jammer like any radio you have broadcasting on Channel 5 endlessless.

You most definatly shouldent make a cell phone app that you can put in front of the camera that just cycles through random plates and includes copies of conststution. I wonder if you can do 10 per second. 36000 per hour all day long.
