I was just watching Enemy of the State at the part when Will Smith is in the cab with the fake Brille and then Gene Hackman is chasing them in the truck, when the fake brille looks in the rear-view mirror back at the truck, gene is driving the car from the right side of the car. Fake brille looks back twice before being hit by gene

then when he passes the cab on the, when will smith looks at the truck, gene is back on the left side of the truck.
