San Francisco is in a central location, by moving the stadium to South Bay it is good for South Bay fans. If you live north of the GG Bridge, say San Rafael or Santa Rosa, you are screwed. If you live in the East Bay you are screwed, if you live in SF, SSF, Daly City you are screwed. Who cares if there is easy parking, there is easy parking in the Stockton, why not move there?
In addition to the comments above, I think tradition means something to the 49ers. I live near Kesar stadium and my family has been going to games for much longer than I've been alive. They are the San Francisco 49ers. Santa Clara may be the easy route to a stadium, but in my experience the easy way is usually not the best way. Working though the crap and getting it done correctly is the way a real person, or a real organization should function. The 49ers used to be that, hopefully the younger York will realize this and buckle down.
It kind of reminds of the Fillmore district here in San Francisco. It used to be beautiful with big trees, large old victorian buildings, jazz clubs, and all kinds of stuff. Well it was dangerous, and the buidings required work, and the decision was made to knock it all down and start over with something cleaner and modern. Now you walk down there and it is 70's buildings and borning strip-mall crap. It was easier to build new buildings, easier to clean up the place when you go in there with a wrecking ball. Looking back, I don't know anyone who would have repeated that. San Francisco lost a beautiful and traditional part of its city. The buildings would have been cleaned up and preserved, and their would have been a feeling of heritage. I feel the 49ers organization and the Bay Area would be making the same mistake by moving the team to Santa Clara, no matter how nice the stadium might be.
