I don't think parking in SF is that bad. I drive a SUV, and just last weekend, I've been able to go to Fisherman's Wharf, Japan Town, China Town, Union Street and find street parking. If you drive to school, parking is bad around the school, but if you are willing to walk a few blocks, you can find street parking. (some are limited to 2 hrs though--but you can buy permit to park all day). All day weekend, and after 4:45pm on weekdays, UCSF garage only cost $1 to park, or ~$120 for the whole year. Besides, you don't have to drive in SF, you have muni right around the corner, and you can go anywhere you want.
Driving is not as bad in SF than in Westwood. The mad traffic in LA is the worst! I am very happy to be in SF with a car. Just make sure when you find apartments, they have available parking space for ya.
Oh, a few of my classmates also drive motorcycle. There are parking spots for them, so it's very easy to find parking for a bike.
The dental school facility allows you to use your left hand at ease. I remember there are chairs in SIMLAB for left hand people. Some of our clinical professors are lefty
More about UCSF apartments, I live in Aldea right now, 1 bed room with parking costs $860. If you are not able to get UCSF apartment, you can get 1 bed room apartment 2 blocks from school for ~$1100. I think this is cheaper than Westwood!
Come to UCSF, you will love it! there are so much things to do here, and you don't have to get stuck in traffic for hours to get there...yes I am talking about Freeway 405.
