Conspiracy or not, that video is as fake as it comes. Whoever has a tiny bit idea about planes will realize that a big plane won't be driving by the highway and since by the position of the plane that's the only possible explanation, then this video is fake. This or IT REALLY WAS DRIVING DOWN THE ROAD
The only way this kind of planes can go straight is in flight (and AT LEAST 200ft high) or on its wheels
