I think Lando is fast for sure - but the difference between a repeat champ like Max and a driver like Lando is that Max is just as good and infallible with a fast car when leading as he is when chasing. He’s robotic in his laps.
I think Lando lacks a bit of that. He’s not as comfortable being P1, or being the hunted. I think Oscar is.
He passed Charles with cooler tires and Charles figured that meant he would have an advantage later - but that never happened. In fact, Charles’s tires went first. And Oscar is so damn steady through it all.
I think starting next year, Lando will be chasing Oscar at McLaren, if he isn’t already.
