I've encountered thousands of cars today. I've yet to encounter a single shark in decades. I'd expect very high danger in the presence of a shark. I've not yet been injured by all the cars I've seen in my life.
People understanding of stats is fine. They understand that the pre-requisite to being attacked by a shark is super-extremely low. That does not make sharks safe. I'll put my hand on the hood of a car any day instead of on a shark.
Your reasoning about Fukushima shows the same kind of problem: it's because of all the urgent actions after the accident that there's not been more consequences. Your argument would show that a house on fire is not dangerous because after people were evacuated, no one died of burning. It's the evacualtion of of a fire that saves life, it's not the lack of danger of a blazing inferno.
