US Motor Vehicle Deaths: ~32,000*
What are people more afraid of? Planes. Why? There's a few theories, but one is people are afraid of dying due to somebody else's mistake, the same with surgery: powerless. Even in a car accident, there's a bit of victim-blaming: the insurance company always says a person could have been more wary.
A cloud failure is much, much more rare, but more scary because we're not accountable. When it happens, we're "more helpless."
