Boo, explain "filtering"... I wear a full face (well, modular flip-up) in the winter and a 3/4 with flip-down visor in the summer.
It is funny how people will treat a motorcycle differently based upon "perception". I remember reading in Easy Rider (back in my more cantankerous youth) a test they conducted in CA. They took an old Harley 'Glide (of course) and give it a custom treatment and dressed the rider as a typical one percenter and headed to the LA freeways. They cataloged all of their close calls, rude behavior from cagers, outright attempts to cause them to assume room temperature, etc.
They then took the same bike, put it back to bone stock, painted it the same color as the cop bikes, dressed the rider differently (in khakis if I remember correctly), and tossed in a cop style helmet. After the "upgrade" they went out to the same freeway, same time, day of week, etc, and ran the same exact route. You probably guessed it, everybody left 'em alone and they had a peaceful ride!
The analysis concluded that the average cager doesn't perceive a motorcycle piloted by your "average biker" as a threat to them as they are bigger, got lotsa metal around them, etc. The subconscious, with lack of threat, then kinda ignores the bike 'cause it can't cause it any harm. Make the sickle look like a cop bike and the subconscious registers it as a "threat", albeit just to their wallet, and keeps track of the two-wheeled varmint.
