By selecting a MP session that shows a multiplayer session is running but there haven't been any lately and I cant seem to start one either . You can start your own also by driving the session, a menu comes up asking to name the session , number of players, public or private game etc. Keep in mind ALL the participants must use the same build , route version and session versions. If you want to host a MP session you would be well advised to run a session on your own to check out all the functions.
