Question about the halo things (I’m only an occasional watcher of F1 and haven’t followed it closely since Gilles Villeneuve died). Why is the piece anchoring the halo to the car dead centre in front of the driver? Surely it would be better to have two of them, each at say 30 degrees from straight ahead, so the driver’s forward vision isn’t impaired?
The vision isn't impaired at all, after the initial period of getting used to it for a few laps you cannot even see it ahead of you.
This above is exactly what drivers had said after it was introduced. Drive any racing simulator that has the halo implemented, you see the exact same effect.
