The best bit about it is you can go out and make a cup of tea, safe in the knowledge you dont need to think about coming in until you hear a car racing round a track. And then you have a 1 min buffer to fish out the tea bag and get the milk in etc. From the time you hear the car start, to sitting down, you have just about the right amount to take it easy without dashing and spilling, usually end up plonking down on the sofa just as they cross the line and Clarkson is thanking them for coming on
