IMO, if the clothes were found near a bend in the road, then yes, someone drunk, high or simply surprised to come upon a young man walking [or undressing] in the middle of the road at that hour, could have hit him. If they had bars on the front of a vehicle, the bars would prevent any damage to the vehicle [the metal bars people attach to pickup trucks, semi trucks or law enforcement/emergency vehicles] to prevent damage from deer, hogs, other vehicles, etc. They are known by different names in different places [bull bar, push bumper, bumper bar, grille guard, etc.] Leaving his body along the road would allow him to be found. On autopsy, evidence would be found [marks on his body, etc] indicating that such an impact had occurred. I would imagine that only certain people traverse that road at that hour, likely locals, oil field workers, emergency vehicles, etc. If someone out there is known to have DUI's, or known to drive fast and carelessly down those gravel roads, LE would be paying them a visit to have a talk. If someone was seeking to avoid public humiliation, arrest, jail time, etc., they could have moved him elsewhere. If this occurred, now they live with fear and guilt. What a conundrum to find themselves in. Feeling terrible remorse for what they did, sympathy for the family, and knowing if they talk now, they are looking at a conviction and prison time. Again, only my thoughts of what may have occurred.
