In an Automobile magazine (October ’14) multi-page article about driving the BMW i3 through Silicon Valley, tucked into a sidebar, I found a little chart: “2013 Vehicle Sales by Fuel Type, San Francisco vs. U.S.” This oughta be good, I thought, and noted that ordinary, garden-variety gasoline-engined cars made up 76.41 percent of the total American market. In San Francisco? 76.88. How unspeakably, improbably … normal.
How is this even possible? SF buys three times as many hybrids (11.39 vs 3.66 percent), four times as many CNG cars (0.04 vs 0.01, no big deal) and nine times as many pure electrics (3.16 vs 0.37). Diesels are about even: 2.69 in SF, 2.98 for the nation as a whole. What they refuse to buy in the City by the Bay, apparently, is so-called “flex-fuel,” gasoline-powered cars that can run on up to 85 percent ethanol: only 5.83 percent of SF buyers opted for flex-fuel in ’13, versus 16.57 percent nationwide. I surmise that on this issue, if perhaps on no other, San Franciscans agree with me: the proper place for ethanol is not your fuel tank, but your shot glass.
