When Ziggy is standing between two cars, in the London area, neither has proper UK number plates.
An identification poster of the two stowaways is shown. The only identifying features listed is that they are both "Caucasian". One actor is of Mexican/Canadian descent and has dark features. The other is of Black/African/White heritage and has dark features. Listing them as "caucasian" is incorrect. Moreover, the physical characteristics below just say 'hair, eyes, marks, height, weight', without specifying what they are.
Ziggy is on the phone to Kendra, with a very visible hand-held mobile, while driving. This is illegal in the UK.
When the investigator leaves the Liverpool shipyard to go back to London, he is driving and being followed through a private estate. The road to London is via motorways, the whole way. And, as already reported they are both driving cards which did not have UK number plates.
On the phone, Bazin (an Englishman) says "I just spoke with him." A British person would have said "I just spoke TO him."
