I'm not sure that Piastri is a nice guy, from a sporting perspective. I think Piastri is willing to do as much as he can to insure that Lando doesn't win a WDC this season. Lando winning the title would solidify Piastri as the other guy, the wingman. He's suddenly Bottas. I sense that Piastri wants nothing to do with that and he'll take the fight to Norris as hard as he's allowed, and maybe a bit more. He has a calm demeanor and seems mild mannered, but I think the guy is really a shark. He fsckin' drove past Norris on lap 1! I don't know what Papaya Rules are specifically, but I'll bet Oscar would happily ignore them.
I'm starting to like Oscar.
