YES! We need a term for this! Naked is good. Companion is good. Shielding is good. When riding in lanes wide enough to be safely shared, mirrors are great for managing the situation as it changes from "shielded by companion" to "naked".
Thanks a lot Nate, for giving HH a vehicular chubb (new term!).
HH, by Shielding, are you referring to riding side-by-side with a car to protect you from other traffic?
