The chilling accident of the Dakar that left Fernando Alonso impressed

Al Qassimi gave several bell turns and withdrew
"I have seen the car pulverized when I have passed it," Fernando Alonso said of the Al Qassimi accident, which he had to withdraw from the competition after several bell rounds in the desert. His car was broken and the pilot could not continue.
It is not very clear what caused the accident; Maybe poor visibility or some problem with the car. But the image is shocking, how the car starts to spin around without stopping, unable to stop.
And although the car was completely shattered, the pilot and co-pilot, Xavier Panseri, walked out of the car, standing and although they were treated by doctors, they were aware.
