When I was a younger man and was in the Navy working on high-voltage electrical stuff, I often had to leave my truck in long-term parking for 3-6 months during cruises. I had a fantasy of rigging something up through my truck that if the ignition switch was bypassed, the steering wheel would become electrified from a high-voltage storage capacitor that would instantly seize the thief's hands to the steering wheel and kill him (most car thieves are guys) by traveling through his arm through the heart and back out the other arm. Then the fried corpse would just sit there and rot as a warning to the next ne'er do well.
. Interestingly, no one apparently ever wanted to steal a truck covered in Dead stickers
Yeah, I might have had some anger issues
