See how Conformer-2 works

Is it going to be a first world championship for Verstappen? Is it going to be an 8th world championship for Lewis Hamilton? Where can Verstappen try and get past Hamilton? First overtaking zone is normally down into turn five. Is verstappen far enough back. He's going to make the lunge down the inside.

Hamilton sees it coming. It's a late lunch by Verstappen who takes the lead of the race. Verstappen now slatches the championship trophy from Lewis Hamilton who's trying to fight back.

No DRS for two laps, so Lewis Hamilton will not get the rear wing open. Now he's going to go down the outside if Verstappen keeps it tight and neat. But he hasn't.

He's gone a little bit wide.
