Honestly 2 years should be enough to have the paddock revised and the track up to FIA standards. Upgrading the access roads will take more time as it's public property.
However it was clearly stated that they will do the upgrades over 5 years time.
What bothers me with this thread is that people are crying about how this will take time and so on, and forget that the BRDC has been promising upgrades for more than 5 years now. You lot should be happy that Bernie didn't take his toys to Zimbabwe, instead you all whine about the GP being moved from Silverstone to Donington, as if it was your life at stake.
People have no belief in the ability of those running the Donington circuit, why is that?!
I find this attitude pathetic.
