Goofs

When the Driver is shifting gears, he doesn't have the handcuffs on his right wrist. But at the end of the movie, he is handcuffed to the case.

The passenger handcuffed the briefcase to the Driver's hand without unlatching it from his own wrist. He also didn't unlatch it from the Driver's hand while he shifted gears before.

When the briefcase is shot, a huge spray of gunk goes all over the inside of the windshield. The Driver only wipes off a small part of it so he can see, but a short while later the inside of the windshield is clean.

When they drive off after stopping on the bridge, the license plate on the BMW Z4 appears to be a California plate. However, when they were chased by the helicopter seconds earlier, the same license plate appeared to be a foreign or diplomatic plate.

When he notices that there's someone following them, the helicopter surveillance shot shows no one is following them.

While the setting is supposedly an African country, the road they are driving down is a US road with double yellow lines. The trees along the highway are coniferous (pine) trees which do not grow in Africa.
