I think the ‘real’ aims of the discussions will become evident soon enough. For me I suspect the FIA/Promoter want the teams to commit to running more cars in the short term to keep the rules stable. I don’t believe this combined Rally 1-/Rally 2+ thing was anything more than a motivation to the teams to negotiate a better field of Rally 1 cars in the short term.
I might be wrong of course, but let’s see.
