I've been very lucky to have been able to give my family and friends an inside view and personal tours behind the closed doors of a few racing teams and super car companies. Usually made a bit more special as we have the factory to ourselves so are free to wander around at our own pace while I look for cool stuff to show them. Be it fully assembled or part built cars, parts made using leading edge technology and materials.
I try my best to explain everything in the simplest way possible so they can relate to what is being discussed but the facts and figures are so beyond their normal level of comprehension it starts to mean nothing to them. Their distant vacant stare and metronome nodding of the head with a few whispered um hum's are the signs that usually gives the game away.
The expression I use for this over loaded mental state is 'greyed out' or with North American guests its 'grayed out'
Last weekend I was on the receiving end of my own very own special factory tour looking around what easily must be one the most extreme cars ever. Over many years I've become quite hardened to all things car speed related but the info. I was hearing was so beyond my normal level of comprehension that after an hour and half I'm not ashamed to say I got to the point where I 'greyed out'
The moment came when sitting in the cockpit, I was fine looking around and discussing the cockpit controls, run sequence etc but totally lost it when I had a closer look at the speedo
