I didn't see who got driver of the day but was surprised to not see Piastri even in there as a contender when it popped up on the screen on Sky. He's got pole, kept the lead for the entire race under immense pressure, multiple safety car restarts even on hard tyres and was first into every bit of rain and kept it on the black stuff. I think that was a top drive and actually, Norris's bad luck kind of detracted from it somewhat masking a great drive. What will be remembered was the engine failure, but Piastri beat Norris fair and square up until that point and drove really well. I feel he thoroughly deserves this championship and will continue to support him.
I guess this may come up again where the Mclarens are 1/2 and might be wary of following closely for most of a race causing overheating. Or maybe it was just a one off. These failures are pretty rare nowadays.
