Also, human drivers kill themselves all the time. Almost 40,000 (or maybe 4,000 — not sure) people die in car accidents every year.
And there are also idiots who try water-cooling their computers by sticking a hose in a slot in the tower and letting it fill up.
Wait, how do you do it?
You only let it fill halfway so the steam created by the heated water doesn’t change the pressure in the case and release the magic blue smoke.
