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.
