Not apples to apples.

Just being near a potentially aggressive bear is a bad situation.

Being near a car or a nuclear power plant is not a bad siuation.

Of course you should run in the other direction if you're close to a potentially aggressive bear.

Same thing if you're in the path of an out of control car, or near a nuclear power plant accident.

But you've got to separate the "probability of bad situation occurring" from the "severity of the bad situation when it does occur".
