That just lets me talk to one to three other people on the same hook-up I'm on. It doesn't let me talk to that guy in front of me who pulls for the same driver I do, or rag the gal behind me when her driver hits the wall.
Fans shouldn't have to buy extra equipment to have a conversation.
Thumbs up to the guy in front of you and a crotch chop to the lady behind you(assuming she's a cool lady)
