Factual error: To start his first mission, Frank has an alarm set on his watch. The watch he is wearing is an Officine Panerai. This brand makes only mechanical watches. But what is heard going off is an alarm on a quartz watch. (The only Panerai with a mechanical alarm looks completely different.)
Factual error: In the first chase scene, when the Transporter jumps his car off the bridge, over the railing, and on top of the moving transport, it would be impossible for his car to gain enough speed to get its front end up so high and get over the railing the way it did, just by driving over the sidewalk edge.
Factual error: When Frank and the dead thug are underwater, with the bad guys firing at them after the oil-fight, if you look, you can see that the bullets from the guns are shooting straight down through the water. Most modern guns (including the ones the bad guys are using) are so powerful, that the bullets shatter upon hitting water, so the bullets we see whizzing about underwater are not real.
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.
Factual error: When Frank dives off the container and goes feet first into the lorry cab his body isn't long enough to do this as he is holding the grab handles on the front of the container, even if he let go he couldn't make it his feet would just reach then he would fall backwards into the road. The lorry cab is too big to achieve this.
