And my comment had nothing to do with downforce or drag, was simply about speed perception on cameras compared to open wheel cars that can even go faster than them.That the closed cockpits and wheels are producing more downforce is just wrong. Everything on top of this car is drag reduction and is used for a calm airflow to the rear wing/diffusor. Pretty much all the downforce comes from the floor.
Closed cockpit and wheels are definitely way better for the drag but have nothing to do with downforce.
