op ed authors note

This is my first draft. I am happy because I found a lot of the things from the prewriting that I wanted to researched, like how many cars had the dash cams and how much each one cost. I am worried because I feel like my op ed is still very similar to the letter to the editor, which means I did one of them wrong, or maybe I did both of them wrong. I want to know whether I did this correctly, as far as the structure, making an argument (that cars should have the dash cams) and whether my examples support my argument well enough.
