Is there not a way an emergency responder, or anyone else for that matter, could fully discharge a battery like the one on a Tesla? As ask coz back in the day before digital cameras became mainstream, we used to repair point and shoot cameras at the photo processing lab where I worked. A point and shoot camera has a capacitor for the flash that can give you a short but not insignificant shock, and to avoid it, we'd take a normal light bulb and use it to discharge the capacitor. I realize a cap batteries stores a lot more power, but couldn't some mechanism be built that does the same thing?
