Someone sent me a video clip of bike racer Bruce Anstey’s record-breaking lap of the Isle of Man TT course – see the bottom of this story – and then asked me: would it be possible for a car to go quicker over the same piece of road, in the same conditions?

And my initial reaction was to say: yes, of course it’s possible. In fact, it’s not just possible but probable.

Formula 1 cars can lap the same circuits used by the MotoGP brigade tens of seconds faster. And around corners and under brakes everyone knows that four contact patches are always going to generate more grip – and therefore more speed – if accompanied by sufficient horsepower.

But then I watched the clip. And then I changed my mind. Completely.
