Piastri is quite mature for his age, he listen to his manager and as you well stated, he keeps on learning, this weekend his team fucked him in more ways than one;

1. A rookie was given his car in practice one, this is not only utterly stupid for obvious reasons (the rookie could have trashed the car or damage it, probably happened either way and is not open information). This decision is stupid since Piastri is the leading driver for the championship, therefore he should have the priority and all his practices allowed.

2. Swapping orders after the mechanics of his team mate screwed up, again, this errors happens and are part of racing, in the same team each driver races his team mate and his mechanics, this decision was simply put absurd and a blatant violation of common sense hence the booing of the tifosi in Italy, the radio telling Piastri it was the rightv thing to do was incredibly hypocritical, I am amazed on how such a young driver could contain his anger in precense of such a blatant betrayal.
