Back in reality though coal and gas and oil actually kill many tens of thousands of people every year in Europe alone, while nuclear is demonstrably, objectively safer (HBO scaremongering series notwithstanding).

It's actually a great analogy you make, because what you portray as the "car that at worst might break down" is actually the thing that kills 1,500,000 people every year (yet many people seem to take as just a fact of nature).
