London Street Grand Prix

A few days ago Santander released a map of London with a potential Formula 1 track running through it. The track passes some of the most iconic London attractions including Buckingham Palace, Trafalgar square, Big Ben and the London Eye.
The track looks amazing and it includes a single lane section just before the start/finish line however this track might be a bit too ambitious. Closing down some of the main roads in London and blocking off quite a few tourist attractions will be a big problem and will probably cost loads! Also, if you haven't noticed, Formula One and all car racing are loud sports and I can imagine the FIA getting some letters of complaint about that.
If this race was to take place in the next few years it would be awesome. It would attract more people to visit London and it would make F1 a bit more exciting from the normal track (like Silverstone).
