I would think it&#x27;s primarily moving people from point A to point B (or, possibly from point C to point D via some stretch in between A and B).<p>[Begin Rant]<p>This brings up the biggest problem I have with Bay Area public trasnportation.  I live 11 miles from work, but it&#x27;s impossible to get there via any reasonable public transportation-based route in less than 1 hour.  On flat land, I can bike at least 50% faster than that, in normal clothes, without breaking a sweat.<p>The BART portion of my trip takes around 25 minutes.  Once I get off BART, my choices are basically to take Muni or walk.  Walking gets me there reliably in around 25-30 minutes.  Muni theoretically gets me there in around 15 minutes, but that&#x27;s in an ideal world where there are no delays on the line and I don&#x27;t have to wait to transfer.  I&#x27;d rather end the day $2.25 richer and get the little bit of exercise than save a whole 15 minutes.  And, of course, the same goes for the trip home.<p>People who live in, say, the Outer Sunset and commute to SOMA or the Financial District have even worse options.  Your Muni trip involves taking 2 or 3 buses, and there&#x27;s <i>no</i> other reasonable way to make the commute than drive (and we know how miserable and expensive driving in SF is).<p>[End Rant]
