That will never happen because "solo mode". Players who don't play open, and there are many, would be excluded from that content. The backers wanted a single player game. FD wanted to make a multiplayer game. They compromised and gave us a solo mode, thus massively restricting the amount of content within the main game that can be dedicated to multiplayer. Because of this, nothing that is a critical part of the core gameplay will ever require interaction with other players. It's by design and I don't think it will ever change.
