How would you imagine one could make driving better, aside from making public transit better? The best thing you could hope for if you feel like you need to drive within SF is to have as few other people feeling the need to drive within SF.

But wait, I have to ask: why do you live in SF?

Practically anywhere else in the US is cheaper and better for people who want to drive.

Very few other US cities are better for people who want to get around by other means.
