It would be trivial to hard wire a kill switch to your fuel pump and have it hidden somewhere so no matter what thief’s can’t drive off with your car. Much cheaper and more secure as cars can be stolen from parking garages.
Really just have to not keep property outside anymore. I used to do the "It's not a big deal, i have full coverage" but had a car stolen and they (insurance) treat you like absolute trash when it happens.
So no more outside for my cars as much as I can
You've said this twice, but what does it mean? I have had my car stolen twice and the insurance company didn't give me any trouble at all and just paid out.
