The MR2 touched the grass at 2:53 and nothing happened, and he spun because he was trying to flick it left way too fast and the grass accelerated the issue.
The S2000 left rear is on the grass for a distance and only spun because he kept the throttle down.
The Ferrari gave it too much throttle back on the tarmac, he was straight all through the grass.
The last one he was already losing it before he hit the dirt.
every spin happens for different reason and just somehow grass is involved it doesn't mean it is the cause.
