Occasionally I’ve logged on an clicked another rider’s name to watch the game from their viewpoint. Sometimes after a few minutes it appears the person I am following logs off as they disappear from my list and the view switches back to me. If I quit the game and log back on that person is still riding. The timer in their status bar at the top of the screen hasn’t reset so it’s obvious they did not log off. The game just sort of turned off their view and removed them from my console.
Not sure if this is an intended result or some sort of bug.
