Believe me you have no idea how bad the effects will be. Not just from an experience stand point. What will happen is, the people will move into these houses/ appartments. For the first year it will be a cool novelty living right next to a race track. Within a year though, that will have worn off and the residents will be demanding the circuit be closed for being too noisey. And if its anything like the residents near airports, who complain about airshows, they will win and Silverstone will be forced to close its doors.
