In a country designed around the combustion engine, San Francisco thankfully has some reprieve from the usual lack of foresight. Anyone who has been to Amsterdam or any number of European cities knows how much more live-able cities are when they don't put the automobile first.

That said, the solution of no right turn from Market onto the freeway at Octavia makes little sense. The better solution to prevent people from being killed, is to have the traffic light allow pedestrians and bicyclists to cross while all directions of auto traffic are stopped. There are several intersections downtown that already behave in this manner.
