The road to sustainability has lanes for more than just cars
That may sound outrageous by today's standards, when cars use about 30 percent of our roadways to handle about 5 percent of the people-moving (a similar ratio to how Americans constitute 5 percent of the world's population but use more than 25 percent of the world's resources). A sustainable, just, efficient mix would drastically beef up the operating budgets of Muni, BART, and other transit agencies, and transfer all the capital set aside for new freeways into new transit lines that would better serve, for example, the Sunset and Excelsior districts.
Alternative transportation advocates insist that they aren't anti-car, and they say the automobile will continue to play a role in San Francisco's transportation system. But the idea of sustainability means beefing up all the other, more efficient transportation options, so it becomes faster, cheaper, and easier to walk, bike, take transit, or rideshare (probably in that order of importance, based on the resources they consume). As Fraser said of residents choosing to drive cars, "We should make it so it's their last choice." *
