That is a good point. Somewhat similar, we seem to accept in the range of 10,000-11,000 drunk driving deaths a year as fairly normal [1]. Because it is, for the most part, a widely spread out set of events with a few cars crashing by themselves, or into one other car... Yet we still drive everywhere. But if you ask people, someone might tell you that they're more nervous flying (despite statistics clearly showing that per hour of driving, or per hour riding in a 777, you're far more likely to die in the car).
