It is f very well sorted chassis no dubt about it. I'm a professional race engineer. To me this doesn't look like all out 110% lap. It's not that he has to start fighting the ill handling car to make it look fast to me . Ask any race engineer - every car on earth when absolutely on the limit will constantly be oversteering/understeering (back and forth during even one corner) to some degree. Very well sorted cars it would not be drastic changes requiring large corrections from the driver. I think some of you guys are actually there - just ask Warren if that lap was him taking absolut maximum out of the car. It's most evident under braking.
Button is good example - as smooth and calm driving style as he is there's a visible difference in his normal lap and qualy lap.
My humble opinion is that there's still more to come.
Can't wait for Syber Evo to show their hand.
Thanks
