What is there to gain in kicking idle players from ranked drift adventure?

I’m not really very technical or network-savvy, but it seems to me if there’s a bunch of users in a lobby/event not doing ANYthing, isn’t that at the very least just a waste of dedicated game and/or network resources? Why tax the system unnecessarily? This game is already slow enough, no need to give it any other reason to be ‘waiting…’

We are part of the event, even if inactive… don’t you see inactive players in free roam too? and they don’t get kicked… at least not in 40 secs!, the system tax is the same if not higher in free roam than in race. And also the game runs perfectly smooth, if anything it’s its network issues that hinder the experience.
