+1 on Bathurst, Spa and Cadwell. Also Monaco and the full Le Mans circuit with the 3 mile straight. For amusement purposes only, sadly.
You might get some of them to ride the IOM TT course but when the motorhome rolled up at the Cadwell paddock there would be tears. "You want me to what ? ...... Fek off "
I'd junk Laguna Seca, Indianapolis, Qatar and Valencia. I'd like to see them use this one, around the Olympic Park: If you streetview this there's actually some decent corners, and there will be plenty of spectator space and easy to get to! I don't think Brands is any better for spectators than Silverstone and the facilities at Donington are legendarily rubbish. I'd also like to see MotoGP go to China, India, Korea and Indonesia.
