Unfortanately, it's also a bit at OAK. They used to have the rental cars right across from the terminal, but they are now just as far away (in terms of time) as they are at SFO.
Being able to walk to your rental car ranks very high in my list of important airport conveniences. It's a disappearing convenience at many airports.
