You may need to seek legal advice on installing anything that could cause harm to someone. Having a remote kill switch activated while its anywhere not in your eye sight is negligent and could kill people, not just the thief. that or any other booby trap is considered premeditative and has landed people in deep water and ruin others lives.
I get it, its happened to me, a few times, stolen motorcycle, had my car smashed and grabbed twice, and even my apartment broken into.
No matter how much $ you have on a policy it still hurts deep down inside. I get it, i really do. but take it from me. prepare your insurance to be beneficial to you. I put $300 cash in stash under the dash were i could get to it and left it there, well documented with my policy. a $200 deductible just paid for itself. its 100% legal. i got 3 times what the bike was worth to me because its replacement value. Protect yourself, its just things, just things, things that will be trash to everyone else once your gone!
