Formula 1 cars are fast. Even a few years ago, when many claimed they weren't, they were seriously quick by any measure. In 2017, they are the fastest cars ever around conventional road courses. The problem is, they don't look that way to many of those watching most of the time.
At Copse during the British Grand Prix weekend, cars were taking the right hander in the neighbourhood of 180mph. That's a corner taken two-and-a-half times faster than you can legally go on any road in the country Silverstone is in. Not that you'd have known that while watching the television coverage - which many of those viewers have to pay serious money for.
Even trackside spectators can sometimes find it difficult to pick out the speed. Silverstone does have some excellent viewing positions, but it also has some less impressive ones. By necessity, often the crowd is some distance from the cars, and it's the same problem for television viewers with cameras often located in far from the optimum places to capture speed.
