I've got a handful of my best segment times by tucking in behind big rigs, cement mixers, etc. I don't consider it cheating because it's dangerous to the point where I can only post it here because I know my wife will never read it. It is a behavior that she would absolutely disapprove of. A paceline is a safe as the sofa by comparison.
Over a long enough timeframe, every Strava KOM will be from a wind-assisted group. That's just how it is. --racer roadie guy from my LBS
