ooh, ooh, what about a naming competition?
Perhaps something that plays a bit of Springsteen? Only needs a couple of seconds of "Born to Run" - the words "Suicide machines" looped over and over when the thing is engaged.
Few seconds of that looping and they'd be paying Tesla for it to crash and burn. Oh wait, what am I saying? They already paid through the nose with a high chance of that happening!
Maybe take my earlier "suicide hotline" statement and combine it with an old kids toy - "Suicide Hotwheels"? Certainly after the batteries go up the wheels will soon be rather toasty..
(Reminds me of the 'capacitance gel' scene in "Demolition Man")
