Theory that is 100% speculation…
Dude smokes spice mixed with weed. He's not used to it. He's trying to drive to Houston. Its getting progressively harder for him to drive. He knows he needs to get off the highway, but he's all f-ed up and he's too paranoid to stop somewhere in town for fear of the local cops rolling up on him smelling like weed, and with weed in the car.
He knows he's not able to drive, but he needs to get somewhere and let this high wear off because he knows whatever he smoke and / or took is getting progressively stronger. He keeps going straight at the intersection and ends up several miles down a dirt road.
Dude has double vision. Is hallucinating who knows what.
Sees something in the road, doesn't know if its real or what, but swerves, overcorrects and ends up wrecked in the ditch.
Then …
A. His judgment is impaired to the point that he runs off in the woods, hides somewhere, succumbs to the elements, and is consumed by nature;
or
B. He's high. He's wrecked his car. He's freezing cold. Standing on the side of the road. He's hallucinating and disoriented. In an act of desperation and panic, he somehow runs out in front of another vehicle and gets hit. His body is somehow stuck to a vehicle or lands up on an open trailer. He may have also been put inside a vehicle by a another human. In any event, his body is carried away from the scene, never to be seen again.
