Judging by the way in which the driver throws the M3 around on the Nordschleife, he certainly knows his way around the car, as well as around the Green Hell.
Alas, once he reaches Schwredenkreutz, he loses the back end while doing around 125 mph (200 km/h) - keep in mind that this kind of speed is perfectly normal for the said section of the infamous German track.
This is the point where the guy behind the wheel starts a prolonged struggle to bring the M3 back on track. However, despite the man's best efforts, the still ends up slamming into the protection barrier on the side of the track.
Since this guy pulled respectable crash save attempt maneuvers, we'll rephrase the usual question - so, what could he have done better?
Well, it seems like this driver is reactive. This means that he tries to anticipate and correct the sideways episodes of the Bimmer. Nevertheless, he would've seriously increased his chances of avoiding a crash had he been proactive.
For instance, he stalls the engine at a certain point during his spin - perhaps trying to use some throttle in order to correct the slide rather than go with it could've helped.
