Isn't it just that we tend to notice and acknowledge first the people we consider to be in "our sub-group" - whether it's the "roadie group", the "walking the dog group", or the "out on a cold day when no-one else is-group"? Cyclists in general are too big a group for me to acknowledge all of them at all times.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
