Left Hand Drive Double Deckers?

[SouthEastBuses]

Correct. Cotral have operated double deckers to/from Rome for some years.

Since 2007 lol.

To be fair, Cotral should get ADL Enviro500s (or even Enviro400 MMCs on some mountain routes that restrict 12m buses). The Apennines mountains in the Lazio region of Italy are beautifully scenic, and so the Enviro400 MMCs (if ADL ever bother making them in LHD lol) can do the routes around the Rieti and Subiaco area, replacing the 10m Temsa Safaris 1501-1590, which are just coaches (Without disability access) that are not needed and a waste of time on the routes they do.
