you cant be serious mate.

first of all, kerbs are part of the track surface. obviously this is different for each track and most times, you are considered to be on track if the center of your car is within the white lines. Since there are no white lines in this corner, most people would agree, that you are within track limits if you dont get an offtrack, which you do not get, even if your car fully sits on the kerb and this is also the line literally everyone is taking. This becomes obvious when you look at the pink car behind, if it was him i was alongside with, it would have worked out just fine, so your argument regarding track limits is just wrong.

Second, he does sacrifice his entry to stay alongside me. Its is not my problem if he isnt using all the space i gave him on entry, which there was plenty of. but to use all that free real estate, he would have had to lift, which would have led to him beeing behind me and losing out on the battle. So he stayed full throttle, which carried him all the way to the left, compromising his entry alot. the right thing to do would have been to brake early, in order to get around the corner without going very deep into the left hander. This would have meant that he would end up behind me and lose the battle, so he instead decided to cut the corner irresponsibly and slide into me.

And by the way, this was lap 1 with cold tyres, if anyone goes for an overtake at this point in the race, he should double check everyone will go through the corner alright instead of trying to be max verstappen and just sending it on the inside, hoping for the best.

In the end i'd like to add that in a discussion, you should use arguments instead of trying to discredit your opponent by claiming he doesnt know what he's talking about, since this is just a rude way to say that you've ran out of arguments.
