Formula 1 has introduced a new safety system that I wasn't all that aware of, as I don't follow F1 all that closely. (As Infernal pointed out its pretty much same old same old over and over.)
They call it the Halo system. What it does is pretty much gives a over head to the formula 1 cars to protect the driver themselves. While I am all for safety I'll admit the thing is quite ugly, and does limit the view of the driver:
Even though this is the case, it did come quite handy in a wreck recently where a fellow driver missed his breaking point and flew into another driver:
There is no doubt that this new safety feature saved Charles Leclerc from serous injury or death, but the question as it goes, does such a device compromise the open cockpit origin of Formula racing?
IndyCar is also looking at the safety standards of the open cockpit, but with a much different approach.
The Indy windscreen is currently under going ballistic testing and hasn't been deployed yet, but looks to be a strong alternative to the Formula Halo, of which Indy took a little criticism for not adopting, but the reason is simple. On a Oval track the Halo would block too much of a drivers view.
Both Series have learned quite a bit from one another. Without Formula there would be no Indy, without Indy a lot of safety standards and innovations would not have made its way to Formula.
In my honest opinion I prefer the Indy standard, as it doesn't compromise visibility to the driver. But the Formula 1's halo has been deployed and has shown promise to aid drivers in the event of a over head crash.
We'll see which way it goes in the time to come, only time will tell.
