Hamilton got a 10 second penalty, which means even the FIA stewards already decided that Hamilton was wrong, so there is absolutely no reason why we are still talking about who is at fault here because it is already decided, Hamilton was wrong and he got 10 second penalty, it wasn't a HUGE mistake, it was a small enough that it was just 10 seconds.
So, what I really think is the simple fact that Hamilton did a small mistake but when you are racing 200+ km an hour wheel to wheel then even a small mistake ends up with 51g worth of crash could be result. This is simply just a very bad situation for anyone involved, but Hamilton got the way. I do agree that it was definitely disrespectful and distasteful for him to be so much cheering when there was a guy in hospital because of him...
I do not know why people are still arguing if Hamilton was at wrong or not, dude literally got a 10 second penalty for being wrong. In order to say that Hamilton was at wrong and caused Max to crash you do not have to say he is a murdering maniac or something, you could simply say Hamilton was at wrong and that's it, nothing more, hell even the penalty is literally second least that could be given, so it was a wrong move but not too big of a wrong move.
I am a huge Max fan but I am trying to look at it from an objective point of view, however even with Hamilton being wrong, hamilton getting 10 second penalty, hamilton celebrating with a full lap of flag waving, hamilton saying proud of himself, hamilton literally saying max was wrong and doubling down, all of this combined, the moment you say "but he got a penalty he was wrong" you are labeled racist for saying it to a black driver, wtf? Like what does his race have to do with anything, he was a driver who got a penalty for being wrong in a move that sent Max to hospital that could have been worse, that is literally the facts we have, stewards decided Lewis was wrong and that's that, just because you "think" he was doing the right move doesn't make him right, I would say Stewards know more about F1 than anyone here... just common sense.
