he made 4 long brake-marks on the ground, so his 4 wheels where blocked. which indicates his brakes where working.
to me it looks like he just went too fast and braked braked too late, like most of his accidents.


i once read a quote from a rally driver, i cant remember from who nor the exact formulation, but i think it was from makinen.
basically i came down to this:
"99 out of a 100 corners can be taken faster than the pacenotes tell, but its that one corner that you have to get correct."
