Imagine telling Tour de France winner Cadel Evans to stay off his bicycle for the next three months, or ensuring Tom Daley's baths don't contain more than a foot of water between diving contests lest the young Briton perform a double somersault from the taps during his morning ablution rituals.
Yet that is precisely the comparable situation Formula 1 drivers find themselves in after the sport agreed to ban in-season testing as part of its cost-cutting initiatives: absolutely no sitting in moving F1 cars between the drop of the chequered flag after a race and 10am a fortnight or so later. To quote Michael Schumacher: "I cannot think of another top line sport where training is banned between events."

By 'training', the seven-time world champion means not a run around the block or a bout in his gym, but the act of strapping himself into an F1 car - the equivalent of Evans' bike or Daley's pool - and burning rubber to improve his own performance, plus that of his machine.
One could largely blame Schumacher for the prevailing situation, for it was during his Ferrari years that testing was taken to the extreme, with the Scuderia making its Fiorano test facility available to its star driver for up to 12 hours a day, seven days a week.
