I've seen plenty of lspdfr mods where there are tons of interactions to be had with an npc when you pull them over. Stuff like traffic policer and even one (can't remember name) where you have a full-on chat option where every one leads to something different (much like an rpg game) but i have not seen a mod yet which adds more interactions for a pedestrian on-foot. It's fairly basic with only four options: ask for ID, citation, warning and arrest. Are there any good mods for this?

I don't remember but LSPDFR+ by Albo may increase interactions with those on foot.
