Rental Car
Parking is expensive in SF and car break ins are incredibly common! Do not leave ANYTHING in your car if you do. You can take a BART Train to the Airport and Uber to the air station for there. OR You can take an Uber directly to the Air station. Fill the car with other guests and it is reasonable.
