Cool, we're sticky! Responses:
Tuscany: forgetful me... it's been added.
Bern(e?): definitely just a photomode/menu location so far, we haven't seen any proof that would lead to a race track.
Rome: the "AGS2009" youtube screenshot doesn't look familiar to me. The stadium track support is an obvious giveaway of such a location, but I'll pop in GT2, run the two Rome courses, and get back with my opinion.
Special Stage "either": Route 5 was clearly featured in PTOM, but I've yet to see any of R11.
NYC street + Midfield: TorqueHappenS, could you please post links?
I'll watch the Citroen GT and FT86 vids again and look for track clues.

Video reactions
FT86: most definitely a new track. That tunnel looked enough like GVS to make me want to believe they completely redesigned it. The rest of that track just makes me happy in regions that shouldn't be affected by a road!
Citroen GT: Looks like some shots at Route 5, London in the evening, HSR, and that jump could be anywhere.
