^^^^ if "paceline" is being used synonymously with drafting, then technically in a crosswind without an echelon there is no paceline but just a line of noobs getting blown out the back
Applied knowledge and skill... you can't persuade some people regardless. For example, last year in an intense Fondo we had pretty heavy winds. In one particularily nasty section with cross-headwinds we were pulling 28mph. There was a national kit clad junior Cat 3 completely petrified of any sort of echelon and was content to ride in the gutter... until he blew.
