I decided to play Muni races today — the 5 against the 21. I’m fairly certain that the 5 line outmaneuvers and outruns the 21. (The block-to-block stops on the 21 draws this conclusion.) But the 5 stops about three streets farther from my final destination (Ashbury and Fell), which is why I always opt for the 21 — pure laziness. But the question was: Could I overtake the 21 on foot once the 5 dropped me at my destination? This was something I’d pathetically pondered more times than a sane person should.
As I waited for the bus on Market and Second, I saw my shot to answer this ever-nagging question. Just behind the approaching 5 poked a 21 — back to back. They both came to a stop. So I decided to test my theory, and hopped onto the 5. After we loaded and left, I watched the 21 out of the rear window until the two buses made the split near Seventh street. The race was on.
