Pictures of what looks like the F82 M4 emerged on BimmerPost which suggest it was a vicious accident. According to the uploader, the driver walked away with minor bruises and scratches which is a miracle in itself but I think had there been a passenger, they would not have been so lucky.
The incident happened in Klerksdorp a few days back and it is certainly safe to say that speed was involved as the car seems to have rolled multiple times. The new M cars are quite clearly very safe cars to drive but this is another reminder to keep to the speed limit on the road and save the lunacy for the track.
