> The reactor that does not exist fails by releasing radioactive fly ash from the coal plant that was never shut down, because nothing was ever built to replace it. Don't discount substitution effects. Your argument would not put safety belts in cars, because the belt that was never installed cannot strangle or entrap its passenger.

That's a non-sequitur, there are alternatives besides coal just like there are more solutions to the problem than merely increasing energy production.

> Can you think of any reasons why a car door handle might be more reliable (for the same cost) as dirigible door handles?

A car handle is only one piece of a bigger machine, one could argue it's actually rather unimportant because if your car handle fails your car still drives, as such I'm not sure that's actually a good example.

How many iterations did we have on cars, as a whole system, so far? Over a century of designing cars and how close are we to a car that never fails? Which should be a way easier task than trying to make nuclear reactor safe, we had more time for it and even way more need for it, yet we are still nowhere close to having our "perfect cars", as such I just don't see how "perfect nuclear" is anywhere in our reach.
