I actually find tremendous value in UID naming. Especially in areas of high interop traffic.
Two of my closest LE departments go by car number, so those are static, and I’ve kept up with portables. OSP seems to have less and less “sliding seats,” so even those IDs have kept static.
Fire equipment almost never changes.
If I don’t have a specific car, apparatus or unit number at least giving them a generic department tag with UID helps.
