Why not have a virtual cafe in some of the Zwift worlds where you can stop/rest up during a s session and chat to other Zwifters.
Or a virtual pub :radost::radost::radost:
Like a lobby? How about when you first launch the game, your are put into this lobby, instead of going straight to the map, and then from there you can chat with other rider and plot your course and pair your sensors even adjust your game settings and kit. Then when you leave the map, you come back to the lobby where can have your post-ride chat or brew before exiting the game and even check out your ride data.
