Once again Jon, amidst a wave of needless, bitchy negativity, you post a reply that is considered & reasonable.
I'm sure that Donnington's owners would spend £100m+ if they didn't think they'd see a return on the investment. Of course that's the way you run any business. ??!!!! For pete's sake (whoever he is). Can we try not to imagine that everything any one ever does is sh1t please? Even if it didn't directly make a return from F1 tickets, it would put the track seriously back on the map in a way that it hasn't been for some time.
As for the traffic- I went to the Renault GP at Donnington a couple of years ago and had to queue from the motorway, 3 miles back from the exit. It took hours to get to the car park. Hey ho. If you attract that quantity of people to a single day event, from around the country, there will be traffic issues. It doesn't matter where you put the event- Silverstone, Donnington or some remote airstrip in the west-country. What are you moaning about?
do or do not. there is no try.
