"The FIA has told Formula 1 teams that they can henceforth mount their rear view mirrors on the halo, as long as they comply with all relevant regulations.
Drivers have noted in the early part of the season that it has become even harder to see anything behind them with the current rear wing regulations..." Link.
In recent years, I've wondered why, given the obvious problems in drivers grabbing a quick impression, via the tiny mirrors, of what's behind them, no one has implemented a view out the back via a camera and a screen on the wheel.
Yeah, I know it's an additional control on the wheel but in my defence, yer Honour, the drivers seem to do a pretty good job of pressing buttons on the wheel at the moment. One imagines that when they look at the mirrors it is for a nanosecond so with a screen the pressing of the relevant button would similarly be for a nanosecond except that in this case the screen is nearer to the driver's line of sight and the image would surely be more informative that one or other of the tiny mirrors the cars currently have.
The image below is apparently of a Ferrari SF16H wheel from 2016.
