Who would've guessed that employing rookie(s) would increase the likelyhood of mistakes? It doesn't make in easier for the drivers when the car is subpar. That being said, Tsunoda in an Alpha Tauri has seen the wall quite a few times as well.
The bigger problem might be next year if the car is somewhere, or at least on some circuits, capable of scoring points. If that is the case, mistakes can't be made. And you can look at it from the angle that all the mistakes hopefully is being done this year, and next year there won't be any. Sure, a valid argument. But I would like to counter that and say that it's one thing to pootle around at the back, and fight for points. The racing will be harder, and you will be on the limit more. So I do wonder if employing two rookies is benefital to HAAS. It probably was in the short term for financial reasons. But will that have an effect upon entering the new era of F1 cars?
