I never owned a car but if and when I do my FIRST choice is 'was this car made with telemetry? If yes, are there clear instructions on how to airgap it'
Also I would want to check the laws regarding the paint on the cars so if it is possible to give it a dazzle or AI confusing pattern. I cannot shield it from ALPRs, but I want as little visiblility against other cameras as possible... Of course doing that pattern makes the car stick out.
