As of now, players who join a race late are put on the first lap of the race. This is unfair in matches where the other players have already reached lap 4 or 5, making it impossible to get something other than last place, or even getting a DnF.
I think players should be put on one lap before the most reached one to give them a chance to compete in the race. So if a player has reached lap 5, incoming players will have to do lap 4 first. It’d still be hard, but it’d be at least slightly fairer.
