Aidan:#bbcf1, external why not use the old Birmingham Superprix track? 200mph up the Bristol Road would be fantastic!
Riccardo: Start in Folkestone, finish in Calais and then back again. With DRS open under the Eurotunnel. How about that for the Europe GP? #bbcf1, external
Rob: How about the streets of Frome? The Uk's newly crowned 'most stylish town' and home to the great @JensonButton, external Even got our own Eau Rouge if you squint really...really hard! #bbcf1, external
