One, I'll never say its too early to discuss safety but it should be done out of respect.
I think Burton bars will help in some instances light impact and most likely would help in keeping a wheel or other object out of the cockpit or the drivers head area. But Im not convinced this would have prevented BC's. This was a massive impact at IMHO the weakest area of a sprint car. The hoop of the cage. there is a video testing Sprint Car impacts, One from the front, one on the cage top. That video tells everything I need to know, that a COMPLETE REDESIGN of the Cage area is needed Either higher or by Triangulating the support of it.or both.
You'll notice these cars are made up of all kinds of triangle. But there is none in the cage area. Just little ones on the corners of it. The car is made to give a little. Ive seen head ons into concrete walls where it will warp the car and make it look like a zig zag. But this is not crushed like I see the hoop area in that video test.
Im not saying you shouldn't get the drivers cover bars. But I think we either need to redesign the car or have some sort of drivers cage inside the car similar to NHRA. top Fuel or both.
Here is a link to that testing video. I left the link so you have to click it to actually go to the video will not stream here. You will see that those bars would have been useless in this kind of impact.
The video is graphic and uses a test dummy. Watch only if you can stomach it.
