Factual error: Frank hotwires the S class Mercedes and steals it. First mistake is to believe that you can simply hotwire an S class Mercedes, you can't, because it has a special ignition key that sends a signal to the ECU. No key, no engine start, no matter how many wires you splice. Secondly, exactly when did Frank break the steering lock? After he starts the car, the camera shot then shows him driving off.
Continuity mistake: In the scene with the 18-wheeler trucks, watch the highway in the background. Throughout the whole scene the traffic behind the trucks keeps dissapearing and reappearing.
Other mistake: When Frank stops to change a flat tyre on his BMW, he finds the flat is his front left tyre. He then changes the right rear tyre.
Suggested correction: No, he walks around the car and sees it's the right rear tire that is flat. The front left tire is just fine the entire time.
Other mistake: The distance and end speed by the guy sliding on the truck's door was too unrealistic considering the truck's speed compared to the background and that it was uphill.
Other mistake: The wheel brace Frank picks up from underneath the trailer has no use whatsoever on a lorry and trailer - it is too small.
Continuity mistake: When the plane with Frank in it swoops low over the convoy and then regains height, the convoy is seen to be at a particular point on the road. After Frank jumps out with the paraglider and catches up with the convoy, it is at the *exact same spot* on the road, despite having driven on in the intervening shot.
Revealing mistake: When Frank's discarded paraglider has blocked the windscreen of the car, causing the collision, the stopped car explodes slightly *before* the actual collision (this is just noticeable even at normal speed) and the explosion is visible in stop-motion as originating inside the car (visible through windscreen) as opposed to the gas tank.
