I get that side shows are inconvenient an dangerous but the acute danger is mostly limited to people who consent to their exposure and it's not like there isn't a huge backlog of criminals who's crimes necessarily create victims in the bay area to be going after.
Edit: While I agree on paper it should be a serious crime to DOS infrastructure I have a hard time taking it seriously when the same government agencies have no problem doing partial or full closures when it suits them.
Additionally many people would happily condone the blocking of similar infrastructure by a few hundred person protest but a few hundred people watching a dozen cars do dumb things for entertainment is not treated the same even if the result is the same.
