Despite the taxi running into cars, walls, etc, it remains in virtual perfect condition throughout the entire chase scene.
When Bryan sets the 5 minute timer, the clock at the top of the phone's screen reads 16:51, when Kim next looks at the timer it reads 3 minutes 24 to go, however the clock now reads 16:42 (9 minutes before the timer was set), the subsequent shots of the timer are consistent with this.
After Bryan notices he is being tailed with Lenore and takes the BMW, he winds up driving through a food stand. Throughout the scene, the car constantly changes between being dirty and covered in food and perfectly clean.
The rear window of the taxi is intact again after getting blown out by gunfire.
The yellow Mercedes Benz taxi that is stolen by the Millses changes from the original launch shape of that particular W124 Mercedes Benz to the facelift W124 model and vice versa.
The U.S. Embassy to Turkey is in Ankara, the capital. There is a U.S. Consulate in Istanbul.
The soldiers guarding the U.S. embassy in this Middle Eastern country would of course assume a car barreling down on them must be a terrorist attack and keep firing their assault rifles and the heavy machine gun. There is no chance to survive this kid of approach in a simple car with no armor.
In the opening scene at the funeral in Albania, the subtitles say the people are speaking Arabic. Arabic is not a language of Albania; it's Albanian, which is not related to Arabic in the least.
Both times that Kim answers her cell phone when it goes dead plays the "off the hook beep". Cell phones don't play this tone, instead it should just go silent and immediately hang up.
In one of the last scenes, where Kim takes her driving test, she gets a perfect score from the examiner. However, when exiting the car, Kim doesn't check her mirrors. A good examiner wouldn't give a perfect score and even could let her fail the exam.
In the chase scene Kim is driving a manual car. She has failed a driving test three times and now driving like a stunt driver.
On the other hand, in this situation she didn't need to avoid collisions, obey any traffic rules, or parallel park, all of which would be required for passing a driving test.
While Bryan Mills and Kim are being chased by Albanians, Mr. Mills gives Kim directions to the U.S. Embassy using a navigator. But the device screen reads "GPS Kapali" which is "GPS Deactivated" for Turkish. Besides, the device screen shows them driving on a coast highway; however, the chase takes place in narrow streets of suburbs then.
Earlier in the film the character of Lenore gets part of her neck cut by one of the kidnappers. Then she is hung by her feet upside down to contribute to the bleeding. Later in the film when Bryan reunites with her, there is no trace of this wound on her neck and their is no scar as if it never happened.
In the car chase when they flee from the police while the daughter is driving, there is a highly controlled slight drift through an uphill right-hander that betrays the skilled stunt driver.
When Kim smashes through the guardhouse at the US Embassy, the resultant pieces flying through the air are made of Styrofoam-type board.
Both times Bryan is watching the time roll over on his vehicle's clock, it makes a clicking sound as though it was a physical changing of the numbers (e.g. flip style plastic tabs).

Later in the film when Bryan reunites with her, there is no trace of this wound on her neck and their is no scar as if it never happened.
When Kim is drawing circles on the map, Bryan tells her to draw them first with a diameter, second with a circumference. Each should have been with a radius.
It is very unlikely that an American teenage girl without a drivers license can drive a stick shift car the way it's depicted in the movie.
When Kim waits Bryan in the stolen Mercedes taxi, a navigator front screen is barely shown. On the screen it is written in Turkish 'GPS KAPALI' means that GPS is turned down. Under this condition it is impossible for navigator to find the address of US Embassy.
After being captured, Mills calls his daughter and asks "Can you get out of the closet safely?" However, she never mentioned she was in a closet at all.
The Istanbul police cars in the movie are very old Tofas brand cars. These cars have not been used as police cars in nearly fifteen years, however they do have the updated police writing and logo.
Kim is shown several times answering her iPhone and it makes a clicking sound. iPhones do not make the clicking sound when answering calls, only when unlocking the screen normally.
At approximately 52:02, as Kim throws one of the grenades on the rooftop, her lips move as if she said something but all you can hear is her grunt.
There is no common border between Albania and Turkey. The Albanians would have to go through Greece, or Serbia, or Macedonia. There are mountain passes, but certainly the border crossing points cannot be that primitive.
So Bryan has only two people on his secret emergency phone? One of them his daughter? It obviously has a touchscreen and at least three contact storage 'slots'. No reason it should not hold a dozen contacts. A well-prepared ex-spook would at least have the U.S. embassy on speed dial, possibly even the police or the local CIA station.
Ever seen one of these funny Internet videos where a new military recruit practices throwing a hand grenade, fumbles it and is pulled into the trench by his instructor in the very nick of time? No way this obsessive father would let his untrained daughter anywhere near a grenade.
Either Bryan uses super secure high tech crypto cell phone technology so his emergency mini phone cannot be located even by the NSA. Why would he do that? OR Bryan's first call to his daughter from that phone could have been traced by U.S. intelligence assets like any other cell phone, in which case he should have insisted his daughter go to the embassy and have the authorities get the caller ID from her cell phone provider.
When Kim sets off the first grenade, Bryan counts nearly 4 seconds and calculates that it was 4.5km away. The speed of sound is approx 0.340km/s so the explosion was just over 1km away. The sound would have taken roughly 13 seconds to travel 4.5km.
When Bryan asks Kim to draw circle on Map. For the first circle, he tells Kim to "make DIAMETER of 3 Kilometers". Then later, for the second circle he tells Kim to draw a circle with "CIRCUMFERENCE at 4.5 Kilometers". Kim draws circles considering both the distances (Diameter and Circumference) as Radius.
When Kim is making circles on the map, she compares the shoelace to the map's scale as a reference, but doesn't hold the lace flat against the map when drawing the circles; instead, the lace acts as the hypotenuse of a right triangle, with the pen and map as the other two sides. Any circles drawn in this manner would be smaller than intended.
When Bryan leaves Kim at the embassy to save Lenore, he memorizes the route, he and Lenore drove, when they were abducted, but that was not necessary. Being a experienced and skilled agent he could just have returned to the house from which he escaped and left Lenore behind. That could not be that difficult to remember with his abilities.
When Murad Krasniqi is talking to Lenore, he calls her Mrs. Mills at least twice. At this time she was divorced from Bryan and married to Stuart, although they had recently separated. If the bad guys had done their homework, they would know this. It is not stated in Taken 1 or 2 what Stuart and Lenore's last name is. In Taken 3 it is revealed that Stuart *and* Lenore's last name is St. John. So she *was* using Stuart's last name during their marriage.
