Post game content.

Ok so can someone list in the base game what will I be able to do after I've completed all side missions and content, like any radiant quests, races, stuff to just chill and do around Night City if I'm bored, things like jobs for example.

Also list any mods that can help add more stuff to do around Night City like custom jobs. My favorite open world games are ones where I can still have things to do when I've beaten all the hand crafted stuff.
