I would place Comettor more as a moon buggy, with the DotM concept including a lunar landing, the white and gold 'astronaut' scheme, planet and stars on the door, and bundled with Starimus Prime. Did anyone else notice RotF Brawns alt mode in the NEST hangar? Kinda cool, me thoughted =o)

But more to actual question, I think scanning military flight vehicles would deem them 'war-like' or 'willing to make war' to the newcomers, confusing them on the Autobot cause. And as far as any non-military flight vehicles go, lets face it, military gets all the cool sh*t =oP In other words, the vast majority of non-weaponised aircraft aren't fast enough or agile enough be of much use against the Decepticons (Cessna vs. Raptor anyone?). Also, as someone else mentioned, it is characteristic of the Decepticons to be, erm, deceptive =oP So for the 'bots to scan war machines when peace and unity is their goal, you have further cause for people to hate on Bayverse for giving the good guys a deceptive or hypocritical tone. So I think sticking to the sexy sports cars for the good guys is easier for the general populace to make sense of.
