Mercedes have released a video, revealing the true extent of the huge amount of work a driver has to do during a lap of the Monaco Grand Prix.
Well known for its unrelenting nature, the 78 laps of Monte Carlo is not only hard on the machinery, but also on the drivers who never get a rest on the sinewy circuit.
Valtteri Bottas was on hand for the video, explaining the huge amount of mechanical changes on the steering wheel that he will have to make over the course of the weekend.
As well as 50 gear changes or so, the driver will also make differential and brake bias changes over the course of one single lap.
As well as that, the dirver has to mentally track his positioning to within millimetres each and every single corner, ensuring that he hits his apex and exit perfectly with absolutely no room for error.
Bottas explained that most of this comes from muscle memory from training and practicing over the weekend, with the instincts forming with every single lap that goes by.
