It should also be mandatory if you have one inside the car it moves the lever outside the car also, which I’m sure most people already do

When I had a push-pull system, I had a cable running from the trunk switch to a lever in the cockpit, Pushing the lever physically moved the rod on the back bumper. Since emergency persons are trained to move that switch, they could possibly turn the car back on. My current setup is a rotary switch on the back deck that cuts all power between the battery and the car. The power feed into the cabin is through a continuous duty Cole Hearse solenoid connected to an aircraft switch on the console to energize it. If something goes haywire I can slap that switch and kill all the accessories and ignition power. There is still one hot wire in the cabin (the battery cable) but the juice isn't going anywhere. It's a quick way of shutting off the ignition and fuel pump without flipping multiple switches.
