21k gun homicides, 43k car deaths, according to your links. And I'm guessing there are orders of magnitude more life-destroying non-fatal car events than gun events.

Also, maybe this is what I get downvoted to hell for, but I'd prefer we focus on making peoples' lives better so that they want to live; banning their access to quick & painless deaths (of which guns are the ~last; most good suicide drugs have already been throttled, helium is now cut with oxygen, and hanging has only a ~70% success rate) seems like focusing on the wrong side of the equation. I want people to want to live, not be forced to continue existing because of the extreme pain of the dying process.
