As one who from time to time works at Silverstone, I can pick out the Italians a mile away. Usually on small scooters, which arrive without number plates as cargo on the large lorries, they will invariably have another Italian clinging onto them - themselves carrying some vital piece of equipment - as they break the speed limit on the wrong side of the road, whilst at the time attempting to keep a dangling cigarette alight. If you do manage to catch their attention the standard reply of course is, "No speekee Inglish"
