Well, it's also not how car problems are solved at UCSC, either.
UCSC is an enclave on a hill with limited transport routes to downtown or the rest of the world. And the UCSC leadership has its hands tied by many different things; they can't just say "OK no cars on campus except if you are a commuter".
Stop trying to solve the problem for California. Focus on the narrow problem. Universities everywhere operate as a parallel population.
