I was thinking, yes thinking, I know...
Don't these things have Lexus telematics, something like on-star? If they are running and I'm not well versed if they even have to be running. Perhaps just power to the black box so to speak.
Can they show up on a radar screen somewhere if this equipment is able to pick up it's location?
Your garage is not safe either. Anyone see how quickly they can open your garage if you have a garage door opener and who doesn't these days?
