Having NYC style density is one thing, actually supporting it is another. If anyone has used the MUNI light rail system in SF it is plagued with constant delays, breakdowns, inefficient routing, and of all things traffic jams. The light rail is also a hybrid aboveground/underground system, and when above ground is not separated from the motor vehicle traffic, which causes more delays. When underground several lines merge onto one track (bart does this too) this is another pain point.
As for bus service thats even worse. One of the original goals of muni was that residences should be within 2 blocks of a MUNI stop. That sounds great on paper, but in reality it makes trips excruciatingly long. When a bus route has to stop at every other block, or in some cases every block, especially on flat terrain, it exemplifies the absurdities of MUNI's grand plan.
