Yes, of course I would like safer trains. I would like safer lots of things, especially cars, because so many more people have car accidents and die each year.
Ideally, our government would calculate lives per year saved versus cost for all kinds of proposed laws and regulations. And then we could more fairly decide which things to implement first, based on which would save the most lives.
This requires us to place a specific dollar figure on a human life, which everyone seems reluctant to do.
