My parents don't want to send me to this high school?

It's an independent high school in San Francisco and I live across the bay in Oakland. Taking BART (the subway) would be the fastest easiest way to get there since it would be too much of a hle for my parents to drive me there each day. It's an amazing high school, my parents do agree with that. But they don't want to send me there because it's in a farther city than I'm used to commuting to for school and they're too worried to send me on the subway. They both know it's where I *really* want to go to school, but they're oddly enough not convinced even after months of convincing and putting together pages of reasons why I want to go there so badly. What do I do?
