I wouldn't say it's simply cost-benefit analysis. It's also scale of accidents.

A whole lot more people die from car accidents, yet there are few reports on national news on accidents. So fewer people care. Meanwhile each time there is an aviation disaster, 100s of people die and it's all over the news for weeks. Similarly with train accidents and nuclear accidents. There where only 2 very large ones but they still haunt the field to this day, while (for example) the deaths from solar installations by people falling from roofs are mostly ignored.

Large accidents have to be avoided, a lot of small ones are more acceptable.
