Other mistake: Towards the end of the film, as the two kids are escaping through the subway being guided through the night vision scope used by the army major, they are virtually blind and have to pick their way through dead bodies, escalators etc. This seems a bit unnecessary as the M4 rifle to which the night vision scope is attached also has a torch attached to the RIS rail. Military spec torches are extremely bright - why not just turn it on? They can't be worried about being spotted, because they are shouting at each other, not concerned with what might spot them.

Visible crew/equipment: In the scene where Doyle is talking to the helicopter pilot at the park, you can see another pilot on the left side of Doyle's head for a split second. (01:14:50)
Question: If the infected can sense the uninfected due to the uninfected smelling clean and scented (deodorant/perfume), wouldn't the closest approximation be to just stop bathing or showering, and not wearing deodorants/perfumes? Wouldn't one rather be dirty than dead? Am I over-simplifying the situation? Do the infected sense the uninfected using some other method in conjunction with the above, thereby nullifying my hypothesis above?
Answer: I suspect that it's really not that simple. Remember that in the first film, Jim was lying alone in a hospital bed for some considerable time before waking to the deserted London. He would certainly not have smelt clean and fresh, yet he was still clearly detectable as prey by the infected. While being nice and clean makes it easy for them, it seems clear that it's not the sole indicator that triggers an attack.
