Much of the internet is highly neurotic people thinking their twisted conceptions of reality are shared by others. I'm not a fan of the bad traffic enforcement in SF, but our family walks everyday, we take bikes to the majority of our things, and only take the car rarely when we need to transport a stroller some distance (our child is not old enough for the bicycle).
Everything is all right but it can be much better. It was even better in the recent past so one could argue it's not at it's best but it's not a warzone.
Traffic violence has become so normalized that you don't even see it anymore. Twice as many people are killed by traffic accidents than are murdered per capita. Your ad hominem attacks do not invalidate the piles of evidence.
Gratuitious is: Unnecessary or unwarranted; unjustified.
If you think that is is unwarranted to describe crashing 2+ ton vehicles into human beings at speed as violence, I would wonder how you would describe it.
