not sure why you're getting downvoted. Traffic deaths in SF definitely went up after "Vision Zero" was implemented
And there are also other facts that point out to Zero Vision being the case. Cities that did not go all-in on this program seem not to have experienced the rise in deaths. I have not researched this in detail, because quantifying the level of road sabotage is tricky. But it definitely _looks_ like it's the case just based on subjective observations.
