During the chase, the driver's window on the convertible is up until they stop. In the next shot it's down though no one had any time or reason to lower it. In the cut after that, the window is up again, although no one was even in the car, or in position to raise it.
The plumber's vehicle has various markings in German. All of them were probably taken from Google Translator because they make no sense in German. Also the phone number is too long and has no prefix.
The street markings during the car chase in Austria reveal the actual location as those are US markings and street signs.
The delivery van has the markings of a brewery called "Weisen Brauerei". That name ("Orphan's brewery") makes no sense in German. It was probably supposed to be "Wiesen Brauerei".
The Austrian police car uses old school flashlights yet in real life it would have used LED lights. Also, the shown license plate is invalid.
The Engineer had no motive to risk exposure (as actually happened) by tracking the exact extent of Voss's losses. His interests would have been served just as well by seeing whether Voss could deliver the agreed funds (as actually would have happened if he had not killed him prematurely, albeit with hidden strings attached.)
