When I had the chance I went over the green part which is more slippery and I even lost more of the car over there, and that was it.
Is he saying that he intentionally put it on the green slippery bit? Maybe that bit is just unfortunate phrasing in a non-native language. But is he then saying that that he was surprised that being on the slippery stuff and keeping his foot in it led to a crash? Or is that just unfortunate phrasing again, putting ‘even’ in the wrong place?
Regardless, as the commentators said, why not just back off once it clearly wasn’t possible to easily get it back from the green bit onto the track? Let it run wider without any major throttle applications and use the nice tarmac run-off.
