I don't like to ride with others, unless we all have helmet communicators.
You and your wife should definitely have them. Waaaaay safer to be able to communicate what you are doing and what you see on the road. It's the same thing as having two sets of eyes looking for potential hazards.
My recommendation on helmet communicators is by

Much further range than FRS, clearer sound quality, and you won't get random chatter from other FRS signals. All collett communicators can speak to other collett communicators. Meaning, that if I were to join you on a ride, we could talk without pairing, or channel selecting. They just work.
