I don’t own a car in SF. I own a Honda Elite 250 scooter and I drive it all over town (except usually I take the bus to Union Sq or the Financial Dsitrict and the cable car to Chinatown). I wouldn’t drive it on the freeways I mentioned even though it’s freeway-legal.
I like the ferry idea too. I didn’t say rachel should drive into town. Parking in Sausalito or Larkspur and taking the ferry to the Ferry Building would be a great way to begin a visit to the City. I just said the traffic isn’t as scary as many people say it is and fear of it should not be the reason to avoid driving into town. Fear of the PARKING situation, though, is a very good reason as is the fun and convenience of the ferry.
