Transportation. San Francisco's Achille's Heel (though the city has many, many such heels). If you look at the heatmap you will see that it corresponds to transportation infrastructure almost to the T. Areas with access to BART are expensive. Areas with access to a functioning MUNI train are expensive (along the J-Church, for example). Outer and Inner Richmond has no mass transit, whatsoever. The Inner Sunset has the N-Judah train, which has about 1/4 the capacity it really needs - i.e., don't count on it getting you to work during rush hour. In fact, don't count on it getting you downtown during off hours either, given its notoriety on breakdowns... From the Outer Sunset to downtown the N-Judah easily takes a full hour. Yes, to go six miles. Transportation in San Francisco is really a clusterfuck. For the second densest city in the US it is positively shameful. Even sleepy Portland, OR, has a better transit system. In fact you can find mid-sized cities in the Midwest with better transit. SF is really the worst-run city I've ever lived in. San Francisco is where people move to live the car-free, urban lifestyle, and then yearn for a car and beg for rides all the damned time. Ultimately, you either give up and buy a vehicle, or you give up and develop legs of iron cycling over hills, or you move to the Mission.
