The front license plate falls off when they are run off the road by the military vehicle. Later scenes show the license plate back on.

When Sammy drives their vehicle at Jesse Plemons' character the other soldier and Jessie are several metres off to the right of Plemons but when it cuts to the impact they are all grouped close enough together that both soldiers are hit by the car and Jessie then by one of the men.
Although set sometime in the future, Jesse (Cailee Spaeny) takes photos with a manual wind film SLR camera. Seemingly having an inexhaustible supply of film canisters, which traditionally only have either 24 or sometimes 36 frames on the roll, she snaps away with abandon, never once stopping to reload or run out of film.
Not all of her moments are show, Not every instance of a photographer reloading their camera needs to be shown, particularly over the course of several days. Furthermore, she has two cameras with her (like Lee), so she has at least 48 photos she can shoot, if not 72.

When Lee is lying on the floor in the White House, some of the shell casings next to her are 7.62mm blank casings. Identified by an elongated brass case in place of where the projectile would be.
Early in their trip, they drive across the median of the highway, leaving deep tracks across the grass. Although it is clearly the only way to get through, there are no previous tracks or ruts at all.

While being pinned down under sniper fire, you hear the sound of the snipers gun before the bullets arrive to camera / characters.
When Kirsten Dunst's character is shot, she is shown in black & white as if photographed by Cailee Spaeny's character. The images show her falling to the floor in a sequence which in fact could only have been captured by a camera with a motor-drive. Cailee Spaeny's camera was a manual wind on Nikon without the accessory motor-drive attachment. It would be impossible to photograph a sequence like that whilst manually winding on the film.
After being run off the road, reversing, and driving away, the engine sound is of a 4 cylinder manual gearbox, while the vehicle has an auto V8 or V10 engine.
The sprinklers in the safe town have the tock-tock-tock sound of impact sprinklers, even though they are continuous flow sprinklers.
