Is it true that deaf people are trying to change hybrid and electric cars to make them noisier since they're getting hit?

I think you mean to ask about the blind and visually impaired. And the answer is yes. I've linked to an Economist article describing the issues.

BTW, I am visually-impaired (though not completely blind), and I do rely, at least partially, on the sounds of traffic to navigate.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
