What I don't like in America (Masha)

It took me time to decide what to write, because I like America and american way of living. Okey, the most things in America. Finally I thought out one thing about the Bay Area. I do not like public transportation here. It's good where it exists. But there are a lot of places which you can not reach without a car. But I came only for summer, I haven't a car here. What should I do? For example, when I go to San Mateo to my relatives, they have to meet me from BART or Caltrain. Of course it's doable: you can rent a car with your friend, attend some kinds of organized excursion or ask someone who lives here to meet you somewhere. But I think it would be more practical if you could go anywhere by some kind of public transportation.
