I didn't have time to reply to this post yesterday and am surprised that no one (that I've seen) has mentioned 5th Square yet. This is a PAC that has vision zero as one of their major issues. They send candidates detailed questionnaires on issues including the ones you're interested in, and publish the answers and make endorsements. I find that information makes it very easy to tell who's on board and who isn't. They don't have their 2023 info up yet but you can look at 2022 for examples of their questionnaires and endorsements. (You have to join as a member to vote in endorsing candidates but any can view the info.) https://www.5thsq.org/2022_election_center
