Maybe US cars :P > They're pretty much the deadliest thing we've ever invented that wasn't actually designed to kill people. It's a box weighing 1-2 tons that travels at 100kmh+. Millions (billions?) of km are driven every year. There will be accidents for both good drivers and bad. This won't change. > cars and shell scripts are perfectly safe if operated by highly competent people, and only become (extremely) dangerous when operated by incompetents, but in practice most operators are incompetent, in denial, and refuse to learn from others' mistakes. That's simply untrue - both points. Highly competent drivers will have accidents. I highly doubt you feel extreme danger when you get behind the wheel/in a car. The way you phrase it, one expects millions of fatalities daily.
