“...but the reason for the collision is unknown.”
Collided with an RPG?
It looks like the driver failed to negotiate a straight stretch of road.
Lived in Egypt for a year back in the late 80s. My work required me to drive out into the Sinai every other week and you would never believe the catastrophic wreck sites I’d see while I was driving. The Egyptians drive with very low or no headlights at night, very fast, and while they’re tired.
I’d pass rigs that were all rolled into a ball, completely burned out with what’s left of driver still in them.
Not a safe place to drive.
