The Jaguar at the beginning of the movie is OU16 LVA. The 16 on UK number plates means the car was registered between March 2016 and end of August 2016. Shortly after, the movie moves to two years later which at the time of writing is the future assuming the film is set in present day.
If no other dates are referenced, there is no reason why the film must be set on the day it is made, or released ; but if the 16 is valid, then the later scenes would have some UK number plates with 18, 68 etc.

Darius Kincaid has a bandage on his right hand when mercenaries attack his and Michael Bryce's car on a countryside road, but the bandage disappears in the next scene when he is walking across a cow pasture.
Before Michael and Darius get dropped off at the Dover-Amsterdam ferry by the van full of nuns, out of the window in the background you can see the NEMO Science Museum, which is actually in Amsterdam, not in Dover. The van is clearly driving through Amsterdam, but after they get dropped off the movie continues like they just took the ferry from Dover to Amsterdam.
When Professor Asimov testified at the trial that Dukhovich killed his wife and child, Dukhovich's attorney objected that this was hearsay and the court granted the objection and excluded the testimony. The testimony was not hearsay. Hearsay is testifying about what someone else said happened. Asimov was testifying about events that he directly witnessed and the testimony should have been allowed.
Car airbags all have two large (approx 5cm/2") holes in the back so the airbag deflates almost immediately after a crash. This is why airbags ALWAYS appear deflated in wrecked cars, so there was no need to shoot holes in the airbags, and indeed the bags would already have been mostly deflated by the time Samuel Jackson shot holes in them.
Contrary to the way it is frequently portrayed in popular culture, Interpol is not a supranational law enforcement agency and has no agents who are able to make arrests. Instead, it is an international organization that functions as a network of criminal law enforcement agencies from different countries. The organization thus functions as an administrative liaison among the law enforcement agencies of the member countries, providing communications and database assistance, assisted via the central headquarters.

When he first appears, Kincaid is shown in leg irons in Manchester. Leg irons are illegal throughout Europe and are not used. Officially.
However, being illegal doesn't means they aren't used, unofficially. Kincaid's wife was being held for no lawful reason, and was going to be released in return for his cooperation ; further examples of illegal practice.
