Verstappen mentioned he felt the system and the principles that include it had been flawed.
“I have not used the vest,” he mentioned. “I am additionally not intending to make use of it. As a result of I really feel like this must be the driving force’s alternative.
“From the FIA facet, they may at all times throw it on security. However then we will speak about a whole lot of stuff that may be improved on security, together with pit entries in sure locations. I believe that has a bit extra precedence than a vest within the automobile.
“I do not prefer it. I do not just like the tubes which might be on you and your physique with the belts that go subsequent to you. Then they’ll say it is a dangerous design. I disagree. It simply must be an possibility for the drivers to decide on.
“Some prefer it, some do not. And that is fantastic. It must be a private desire. I do know, in fact, this 12 months we will (select). However most likely subsequent 12 months they do not need to try this. And that’s not the appropriate factor.
“The issue is also that in a GT automobile or another automobile, prototype, you’ve got a bit extra space to place stuff, or at the least cables.
“In our cockpits, it is so slender that there isn’t a area, or at the least not sufficient area. And that’s additionally slightly little bit of an issue I discover.
“Plus, the place are you going to place the dry ice? The vehicles usually are not designed actually to have this further type of area. And inside 15, 20 laps, it is anyway gone. And you’ve got scorching water (working by means of the system).”
Verstappen’s final comment highlights a problem with the system whereby if the dry ice can’t be stored chilly for lengthy sufficient, the fluid within the system takes on the ambient temperature across the tank.
As F1 vehicles attain temperatures exceeding 40C throughout races, meaning the liquid pumping by means of the system would make the driving force hotter somewhat than cooler.
However Russell mentioned: “I will run it. I ran it in a few races this 12 months. It is not the right answer but. And the actual fact is, you don’t have any testing, you’ll be able to solely check it in a race setting.
“So, the race in Bahrain, I used to be pleased with it. I ran it in Saudi as properly. I used to be pleased with it. However, in fact, right here it’s a lot hotter. The dry ice will soften quicker.
“However the workforce have made massive enhancements with the automobile cooling of itself. We recognise some fairly main problems with kind of scorching air seeping in.
“The cockpit massively exceeded 60C at sure races and simply shifting just a few digital packing containers round and hydraulic traces which might be working at 120C round your toes have a serious affect on the warmth. I will provide you with a solution tomorrow (as as to whether it labored).”
Championship chief Piastri mentioned: “I nonetheless do not know if I’ll use it. I used it yesterday. I believe the issue with the go well with is it is nice when it really works. But when it fails, it is even worse than not having it.
“I believe the initiative is nice. However, like Max mentioned, I believe having the selection to make use of it or not is vital as a result of there are advantages and drawbacks.”
The cut up within the prime three is anticipated to be mirrored up and down the grid.
