Locality is a restriction that if something has an effect, it must do so through some field or propagation that is present at the point in spacetime where the effect occurs. Non-locality undoes classical causality, with effects occurring over so-called spacelike intervals. This opens the door to the future influencing the past and so on. It's an expensive constraint to break.
But as written, the PSR doesn't require causes to be in the past, it works with retrocausality. The laws of physics are time symmetrical, so causal relationships work both ways in time. (Your arrival at the intersection is necessitated by the crash you have, etc.)
I'm fine with probalistic explanations, but are these not contingent outcomes? A scattering electron will obey a deterministic distribution of possible outcomes, but the precise outcome is a contingent fact, not derivable from a cause (except if you sacrifice the normal understanding of causality, per Bell).

Everything is contingent until what happens and reality occurs in the moment, but everything that does happen when reality occurs in the moment is in accord with PSR, so therefore seemingly everything has a sufficient reason.
