Car alarms are utterly pointless, no one pays attention to them. Moreover, most of them are terrible at energy management and will drain a battery flat. A better security option is a secure relay that completely disables the entire power system of a vehicle until a physical key is inserted and turn to close the relay. Now, most humans being the useless, lazy fucks that they are will undoubtedly just leave the key in and turned on. However, if that is found to be the case, they should get zero payout from their insurance company if their vehicle is stolen and lost or stolen and damaged. Make the relay box out of Inconel or Boron steel so it is extremely tough to break in to. I would guess most people are going to notice someone in their driveway or on their street with a gas powered angle grinder or a plasma welder.
Thinking it through a bit further, when the relay is locked open, the vehicle should lock the differential, the brakes, and the transmission, too. That way a shitbird thief can't simply roll it away.
This sounds like a great idea. A boron steel relay box would not cost that much either. My vehicle already has a shield for catalytic converter protection. I'd like an alarm that works in coordination that just laughs at the attempted thief and calls them an idiot.
