@xian >the device that gets banned for being "easy to steal cars" with
You can't even steal a car with a flipper anyway due to how it doesn't have the right hardware.

Sure you could technically mod one with extra hardware and steal a car with that, but that's the extra hardware and not the flipper.

Car thief's just go online and purchase "emergency start" devices that are disguised as portable speakers, find a modern car, pull off one of the headlamps (full of proprietary software), plug the disguised device into the CAN bus, send the unlock+start signals, then drive the car to the chop shop.
