Taking a benefit from the BL track.

As I said above, insim wouldn't be a real problem because you'd choose at the start of the track the path you want to race , track/rally. So if you'd choose rally it won't switch back to trackmode when you got the road section.
And I do understand your point that what happens when both parties meet on the road, but I'd say this is less likely to happen. We can all see how many people use the track at a time, chances would be low for the rallycrosser's to leave with slow speed and crash with someone from the track(my opinion), and even if you wouldn't agree with this, the points where the rallycross section joins, has a pretty wide road so it makes it even less 'hard to pass if needed'...
