IIRC an abundance or lack of the Problem element can be solved by an abundance or lack of the Solution element, and you can pair the positive / negative charge however you want.
McQueen not using the pit crew sounds more like a lack of Hinder than a lack of Help, i.e. he refuses to be held back, he won’t accept slowing down the race to be fixed up. Later, he has to deal with too much Hinder when he’s saddled with the asphalt machine. Notice that regardless of whether there’s too much or too little of a thing, the thing is still the problem. But then McQueen Helps the old car across the finish – problem solved in both MC and OS.
