How come when Carly drives the Mercedes-Benz SLS AMG to her apartment / house none of the Autobots that arrive (Dino, Sideswipe on the street and Bumblebee, Wheelie and Brains in the house) Know its the Decepticon Soundwave? Wouldn't they be able to detect its a decepticon? In ROTF Ironhide said "hes here i can smell him" so why can't the other autobots.
And even the detector's they mentioned in the movie that are on the streets can't tell the Autobots there a decepticon just feet away from them
