... and in this particular case it was the kerb that launched the car.
They need a strip of grass or gravel or even a step, so pilots don't consider the runoff "normal track".
It's absolutely moronic that one can not only post a lap time while going outside of the track (Vettel), but now times can also be set under a Red Flag (Bottas). :facepalm:
Summary
Leclerc wins after Hamilton accuses him of dangerous driving
Hamilton and Leclerc battle hard for lead, but Hamilton loses place after leaving circuit
Vettel penalised after spin and hitting Stroll coming back on track
Sainz, Kvyat, Magnussen out
That's my point exactly, you dont go out there if there is no surface to run on. Then you dont need a sausage kerb that launches the car. At worst you get a Warrick type incident.
