It's an emotional response though, like how there are still more people with a parallizing fear of flight that don't have a problem hopping into a car.
Like I said, I'm not justifying being against Nuclear, but explaining the challenge with Nuclear's general acceptance, there is a fear response from people, and it'll need to be curbed and addressed. That fear response is due to the grandiose nature of a Nuclear failure which fossil fuel don't have, even if they kill you slowly and might lead to world ending catastrophies.
