The halo enters F1 for '18

[Starter]

Apparently , they will be installing rearward facing cameras to the halos , making it possible to actually see the moment the red mist clouds the driver's eyes as he's brake tested or squeezed off track .
4K high def customers will be able to count nose hairs and see the track reflected in the beads of sweat on the driver's face , further enhancing the overwhelmingly positive experience for all concerned .

And those are just the highlights of the experience.
