People also tend to object to "move fast and break things" when they, and their very expensive buildings, are on top of said things and get broken as a result.

Point. Although I'd assume the majority of subway routes tend to be built under roads (also bad, but less terrible)?

Not sure what the geology of San Francisco / California tends to be like, but I believe most of the Manhattan skyscrapers are anchored down to the bedrock. Which I'd expect would require cutting and reinforcing vs just "drill on through".
