Other mistake: When John and Zeus are being chased by the German guys in the car, John asks Zeus to pull out all the fuses in the fuse-box. The next shot is a quick shot of the speedometer etc. and it is lit up. Surely if all the fuses were out it wouldn't be lit?
Other mistake: The winch attached to the front of the black pickup isn't particularly big, and its size governs how long the cable can be. From a side shot of the winch cable stretching from the pickup to the boat, there's no way the cable being shown comes from the winch on that truck: it's too long, it would never spool back onto the winch.
