Continuity mistake: After The Thief flees the junkyard and is on the highway, the background changes numerous times, especially when he is pulled alongside the road talking to the lady who was in the trunk. Most obvious is the back-and-forth switching among wide conical-shaped pine trees, tall leafless trees, and thinner pine trees. Trees don't relocate themselves, so a green screen was being used. The Thief also appears to pass the same embankment twice. (00:08:49 - 00:10:48)
Continuity mistake: During the getaway/pursuit from the motel, The Thief's front side window was up/down to various distances (from closed or almost closed to about 3-4" down). After the collision, the window was up but as soon as The Thief turned his head to look in the backseat, it was down a few inches. (00:36:24)
Continuity mistake: The Thief drove away, stranding Mia alongside the road. After Mia shouted, "Seven AM tomorrow, Ravenhill Hangar!" the Thief's car was closer to her (i.e, it had not traveled as far). Also, The Thief peeled out (making noise), had his windows up, and traveled far enough that he would not have been likely to hear what Mia was shouting. (00:14:30)
Continuity mistake: The Thief pulled half-way off the road onto the shoulder, with the middle (length) of his car aligned with the solid white line. When he was pulling out, about three-fourths of his car was to the right of the white line. It is also a "stupidity" leaving half of his car blocking the lane when the shoulder could have accommodated most, if not all, of his car. (00:09:30 - 00:14:30)
Continuity mistake: The way the cars collided did not match subsequent views. The cars were at different angles (which changed a couple times) and the junkyard cars (some of which were not initially there) also had varied appearances, such as a missing door and trunks/hoods open or closed. The aerial view after the collision was not what would be expected and the green car looked gray or pale blue. (00:03:50 - 00:04:24)
Continuity mistake: Smoke was no longer coming out of the wrecked car when The Thief had his back to it while he was shooting at a thug's feet, but it resumed when The Thief turned around to face the car. (00:05:20 - 00:05:43)
