Continuity mistake: When the tanker is blown up by the rocket, the driver runs off to the left. Cut to the long shot of the tanker blowing up and the driver is gone.
Suggested correction: The driver was engulfed and killed by the explosion, as he wasn't able to get away in time. That's why we cannot see him, as the scene was supposed to point out that the driver didn't survive.
Continuity mistake: When Sanchez gets in the petrol tanker at the end the two drivers from the crashed one are in front of the one that's on fire. One is lying down, the other injured, but when the trailer blows up both men have disappeared.
Suggested correction: These men disappear because the explosion kills them. They are in a state of immobility and are unable to escape the explosion.
