What about the way everything from Abbey to Woodcote was pretty much single-file only? As the cars developed more and more downforce, the challenge of Bridge was killed off.
Although I am surprised that Silverstone didn't try and snare the World Rallycross Championship, seeing as how it is the Home of British Motorsport and Lydden Hill is rubbish. Send the cars up the Wellington Straight, cut across the run-off to Village - Aintree, the Loop and Farm become the joker - then down to Abbey where the cars turn right and take the old circuit back to Wellington. Sure, it means turning the old circuit to dirt, but it means that it gets used again. And seeing World RX cars drop through Bridge would be a sight to behold.
