Sorry if it has already been mentioned, but I just realized that in BeamNG there could be a thing that no other rally game/sim will have. And it could be done fairly easily, well at least compared to other sims. It's realistic rally course where you are not just being spawned in to super stages, but the whole course with driving between stages and time management, with traffic and even cops pulling you over for speeding, also maybe some kind of roadside repair or tyre change system. That would be whole another level.
Agree, this is the thing that could make Beam better than other rally games in my opinion (if its not already), the driving between stages through traffic with a falling apart car would be awesome. Potentially have 1 championship per map or something with driving between events, and then once the championship is complete it goes to another map.
