The driver of this car is okay and escaped with only minor injuries. He explained the event as follows:
“Realizing I was going way too fast for that section, I applied the brakes softly in an effort to keep the back end from sliding out, but, combined with a bump and rough switch in surface texture from concrete to asphalt, I lost traction. I began sliding to the left, the car oversteering, rotating counter-clockwise, over the center marker. I counter-steered, turning the steering wheel all the way to the right, but kept sliding to the left into the turnout. It was at this moment I knew, I had fucked up.
I slammed into a berm and expected to come to a complete stop, but the terrifying journey wasn’t over. I went over the edge. It happened so fast all I can remember is everything crashing and spinning. I thought I was rolling over down the side of the mountain. I was confident I was going to land upside down and get crushed. I was on the world’s worst roller coaster that could only end with death, or so I thought. I came to a stop, still yelling, not fully comprehending what just happened, or how far down the mountain I was and that I actually just crashed my car. Luckily for me, I landed on a rock wall that was part of a drainage pipe that went through the mountain. It was the only horizontally level piece on an extremely steep sloped hill. Had I spun off a few feet before or after, I’d be dead.”
