For the benefit of FIA president Jean Todt, I shall choose my words carefully. He doesn't like public criticism for the sake of it.
There is a problem with the design of the halo device that should be addressed. It is not the aesthetics of the halo itself; this is not yet another 'oh doesn't it look just terrible' rant. The problem is an unintended consequence on the overall visual identity of the car and the person driving it.
Every pre-season, without fail, drivers in all categories proudly show off their new crash helmets on social media. The trouble is that from now those helmets being used in F1 and other halo-protected categories are going to be very difficult to see.
