i agree top gear track is NOT a race track.
also they have missed out Blyton, Nutts Corner & Tockwith & a whole load of stockcar ovals.
there are a few hillclimbs in UK that might qualify but they dont complete a circuit.
The width of a race track does not make it any more or less of a race track.
Take Cadwell Park for example, the last sector is quite tight, I think it would be a struggle to get 3 cars wide without having 2 wheels on the grass.
If you include drag strips then theres also Shakespeare County raceway. Carnaby up North somewhere, Dundrod and the Northwest 200 if you consider Ulster to be British...
New Brighton is a street circuit so is the Superprix so they shouldn't be in that list, and you can't test on the Top Gear Track, and there is, and never has been an official motorsport authorised race there anyway. the Top Gear Track is just an airfield. It's not something to be in that list, no actual racing even goes on there... Santa Pod is a dragstrip only, if thats on there, then Avon Park should be and so should York raceway.
