The retired boston police commissioner has done an ad spot for Yes on Right To Repair specifically to slap down the "you will be raped in a parking lot" FUD: https://www.youtube.com/watch?v=0bye5DRBSpw
The EFF is also strongly in favor, naturally, but i think Ed Davis will pull more weight if anyone's undecided.
(when marijuana legalization was on the ballot in 2016, the then-chief of the state police did a similar ad spot whose pitch boiled down to "vote yes so we can stop wasting our time on stupid college students, willya?", which I think had a similarly large impact. )
