Humans Invent has been given a rare opportunity to see what goes on behind the scenes at McLaren HQ. Once you’ve finished gawping at the selection of past racing cars, including Jenson Button’s F1 car, dotted around the main hall, you begin to realise how precise and obsessively clean everything is, so much so that I started to look in earnest for any dirt or blemishes on the floor tiles and found only my reflection. The place is also unnervingly quiet. Uniformed, trainer-clad employees move purposefully through the building without making a sound.
