Does WATCH_DOGS feature a "quest generation"?

I've somehow read that I cannot fight against Gang Hideouts after I cleared all of them. Is this also true for other quests?

So when I do everything I'm completely done with the game and I cannot play these Jobs again?

Or does Watch underscore Dogs festure some sort of random quest generation? (For example pick 2 random locations and 1-10 random vehicle, let them drive from A to B and call it a "criminal convoy")

I hope someone can answer this question. Thanks
