Considering that this is a Garry's-Mod-only thing: probably yes, because you'd need to code the whole thing yourself. The biggest issue with stuff like this is that BeamNG does not have a navigation mesh system like other NPC-focused games, at most the roads are mapped out. You'll have a really hard time implementing anything beyond Billboard-plane nextbots with scary JPG files plastered on them using roads to move around, and I'm not saying that this is at all simple for a beginner either.
