AI in My Team good car vs bad

In my first few games I set up my team to be at the top end of the field, using an AI that had me roughly competing for poles and wins. I though I would try a game with my team at the bottom and supposedly the car is by far the worst with my teammate at the very back.

Using the same AI levels I qualified 10th in Australia and won the race and because of rain started last in Japan but finished 4th. I don’t remember the previous editions being this easy for a bad team.
