Let’s start with a little story. A few years ago, I was invited to attend a demonstration of a high-end simulator, and asked a driver, a multiple winner of the Spa 24 Hours, to accompany me.
The simulator engineers asked me if I could sit in the car and give my impressions. I told them that I thought I was a decent driver on public roads, but did not think of myself as a good racing driver. Nevertheless, they insisted, and I went so I sat in the car.
The car was in the virtual pit lane, and an idea crossed my mind. I asked the engineers if all systems were recording. When they said yes, I turned the steering wheel 90 degrees to the left, and then 180 degrees to the right, before returning it to the initial position with a last movement of 90 degrees to the left. To the surprise of those around me, I then got out of the car and went to the control room, where I asked to be shown each tyre vertical load and front ride height variations.
There were none! After the control room engineers confirmed that every virtual sensor and / or simulation inputs and outputs were properly recorded,
