First let me assure you that the driver is alive and well and lived to tell the tale. He personally uploaded the video on YouTube.
I want to start by saying that driving on a twisty and unfamiliar mountain road is a very stupid thing to do.
The video is filmed by a camera attached to the rear lateral window of the BMW showing the driver pushing the gas pedal to the metal, pursuing BMW M3 E92 on a road in Arizona. Watching the video, we can agree that he is driving much faster that his capabilities and because of that he’s surprised by a tight right turn which made the car understeer and roll over down the cliff.
Take a look.
There is also a tribute video for the car uploaded by the guy himself captioning the video “died doing what it was engineered and built for” which is pretty funny and I got a feeling you will want to comment on that…
