There is no way to work out which car it’s coming from without a bunch of sophisticated hardware and effort.
Have you seen how these people work? They drive up, stop next to a car, tap the window with a window breaker, pull the chair down to look in the boot, grab anything they find, then drive off.
In and out within a minute. No time to be dicking around with Bluetooth scanners to see if there are MacBooks around.
You are very incorrect, but there's no point in going back and forth on this given how far off we are on claims.
Suffice it to say I have talked, personally, to enough bippers to understand that there are 'spotters' and 'bippers', and which one uses the cell-phone based Bluetooth scanner (which requires no 'hardware' or 'effort' to figure out the source of a BLE signal.)
