I did exactly what pastymuncher did today, switched off 1/2 way through. I am on an old Sky package where I get the F1 channel as part of the HD package so I only pay £30 per month for that and the boxsets. But I am really hoping that F1 bring out that F1 TV Pro thing for the UK but I assume that won't be for years as Sky have the rights and god forbid it gets aired somewhere else.
On a side note, the F1 channel have been uploading so much content to their Youtube channel recently, including Qualy and Race highlights. I know cutting down a 90 minute race into 6 minute highlights isn't ideal but for races like today, it's perfect!
