This video is several things. It's horrific, to start with. It's also flat-out amazing. The crash looks non-survivable... the driver flying through the windshield looks non-survivable... and his landing on the pavement and sliding into another booth, yes, looks non-survivable. But despite all of that, the man is ALIVE with non-life-threatening injuries. His passengers in the car? They also survived!
The Florida State Trooper who responded to the incident indicated in his report that the driver of the vehicle appeared to be fatigued at the time. This means he was more than likely falling asleep.
The Florida Department of Highway Safety and Motor Vehicles says "Getting behind the wheel while fatigued can have dangerous, and sometimes deadly, consequences. If you’re having difficulty focusing, frequent blinking or heavy eyelids, pull over in a safe place to rest before continuing to drive."
