If that's the proposal then I don't see it getting very far with Bernie. It has no oomph.
If there is going to be a Rome Grand Prix on the streets, then it has to take in much more of the stunning architecture, be not so far away from some of the ancient ruins. Imagine the Colosseum in the backdrop etc.
Otherwise... it's be like a London Grand Prix on the streets of Peckham, or a Paris Grand Prix with out the Eiffel tower in site.
Obviously my street knowledge of these venues is lacking, so I'll make that clear now if anyone wants to provide [citation].
