I think they need to implement the rally special event into online rally events. It would be pretty fun to have random generated p2p tracks and rally against other people.
Or create your own stages using the course maker and making it into an online rally event. If you make all sections of the course with the smallest width possible, it isnt to "wide-open" and would make for some fun online rally action.
EDIT: In fact, I wish they would have a rally centric DLC with current/new 2012 WRC cars, maybe some standard to premium upgrades of the Group Bs (or the Escudo!), then have a track pack with Pikes Peak, and the ability to make p2p in the course maker and create online rally events. I would pay $25-$30 for something like that!
