Sounds like you are not very familiar with SF.

It's an easy drive south on the 101 to get to the rest of silicon valley, without the horrible traffic/congestion of downtown SF.

Also, unlike many neighborhoods in SF, there is superb muni access and also great proximity to golden gate park AND ocean beach. What better outdoors space could you want?

I lived in the outer sunset for a few years and it was among the most livable of the neighborhoods in SF that I frequented.
