Upgrade the facilities. One of the reasons why the Silverstone Wing was built was because the old pits were sorely out of date. The garages used to leak, and the teams had to bring their own flooring to make sure they had a level surface to work on. The BRDC used to pride itself on being the heart of British motorsport and Silverstone the epicentre of Formula One, but they neglected it something fierce. Prior to the Silverstone Wing being built, the Silverstone pits were as bad as Montreal's, which haven't been updated in thirty years. But at least the Canadians have the excuse that the Circuit Gilles Villeneuve is built on an artificial island and so it's very difficult to redevelop when you don't have the space to do it. I know it's popular to mock Bernie for wanting circuits to invest in fancy new buildings that look nice on television, but the old Silverstone pits were a shameful shambles for years while the BRDC resisted any infrastructure updates. Even now, there are sections of the main grandstand that don't even have overhead cover.
But hey, the BRDC got a brand-new clubhouse. It's the perfect place for old dinosaurs to reminisce about the glory days, blissfully oblivious to the way the circuit crumbles around them. Like I said, they're so concerned about the history of the British Grand Prix that they forget about its future.
