When Driver rams into Nino's car for the second time to push him over the cliff, he's shown to ram into the rear right door. After Nino's car tumbles down the cliff, there's a huge dent on the right front fender.
During the initial chase Driver realizes they have been spotted on the bridge by the police helicopter. He immediately puts his foot down and the engine sound suggest fast acceleration. However, the distance to the other cars in front hardly changes in the following scenes, if at all.
When The Driver opens the door for the robbers at the beginning of the movie, you can hear the car make a beeping noise. This "key in ignition" noise only plays when the driver's door is open, to prevent locking the keys in the car.
In one scene when Driver and Irene are talking on the phone, Driver is seen using a cell phone. When the shot cuts to Irene, we hear Driver hanging up with what sounds like a landline phone being put back on its cradle.
During the chase scene after the pawn shop heist, Driver maneuvers his Mustang 5.0L backwards down a canyon highway. Although the Ford Mustang only has one reverse gear, the engine sounds played suggest the shifting of gears for a manual transmission.
A television shows the Los Angeles Clippers playing the Toronto Raptors in the opening scene. Later, while Driver waits in his car, the radio announcer calls the score of an NBA game between the Boston Celtics at 77 points and the Los Angeles Clippers at 72 points. Moments later, after announcing the Celtics scored, the radio announcer states the score is still Celtics 77, Clippers 72.
When Bernie visits Shannon's garage to see his newly acquired stock car, Nino criticizes Bernie for making the purchase and expresses his preference for a 1955 Ford Thunderbird. When the scene cuts to a conversation between Bernie and Driver, the Ford Thunderbird is no longer seen in the garage.
While stealing a Mustang GT, Driver can be seen wearing his driving gloves as he walks up to the car.

During the initial chase scene, Driver takes off his watch and straps it to the steering wheel in the Impala. When parking in the stadium, he rushes out of the car, but later when he drives his own car the watch is back on his wrist.
When Driver is waiting for the robbers, the right rear door is open before Driver opens it. When the first robber exits the building, the door is still open. In the very next shot, Driver opens the door for the robber to get in.
At 44:38 into the movie and during the chase after the pawn shop robbery, the camera cuts to a shot of the girl in the back seat showing the chase car being flipped in slow motion. Just to her left shoulder on the rear interior deck of the car is the Iconix HD camera that is used to photograph some of the case scene.
When Driver is obtaining his Chevrolet Impala for the heist, he is told that the stock engine has been swapped for one with over 300 horsepower. In reality, that generation Impala already had an available engine with over 300 horsepower.
When Shannon is in the garage talking to Bernie about the race car, he says that the tire treads are still in good shape to assure Bernie of his purchase. Treads on NASCAR-style stock car tires are a bad thing. Stock cars use tires without treads to maximize grip on racetracks.
Obviously flipped footage of Driver when he first spots Irene and Benicio standing with Shannon at the garage. In addition to the text on the lift being backwards, his hair is parted in a different direction and the brown patch on his denim shirt has jumped to the other side of his chest.
The production used two different Mustang GT's while filming. One, a 2011 model, is equipped with the 5.0L engine. The other is a 2010 model, which looks identical but is equipped with a 4.6L engine. All 2011 and later model Mustangs equip a wide view mini mirror, which can be seen when Driver steals the Mustang before the pawn shop heist. In the chase following the heist, the mirror is a regular full-on driver-side mirror without wide view, last used on the 2010 model.
The goof items below may give away important plot points.

Towards the end of the movie, Nino's car is pushed off the cliff by Driver and Driver is standing on the cliff looking over his car, which is in perfect order despite having just been in a massive head-on collision.
