I really really hope I am wrong, but I don't expect any more drivers in the mix. The current Rally1 drivers are (for the most part) in Rally1 for a reason. They will continue to be the best even in Rally2 machinery.

Additionally the factor money cannot be understated. You cannot compete with toyota as a private team or individual. They will optimize every screw in the car if need be.

What should get better though is new drivers adapting better to Rally1. The jump from Rally2 to 1 was just huge
