Former Indianapolis 500 winners Scott Dixon and Will Power tested IndyCar's new cockpit protection device on Wednesday, and both drivers gave the aeroscreen their endorsement and said it was already fit for racing.
The aeroscreen, which is designed to protect drivers from flying debris, covers the open-air cockpit and is anchored by a titanium framework surrounding the driver.
Both drivers tested the aeroscreen at the Indianapolis Motor Speedway, and after their sessions said they could not imagine driving without one on their car.
"When you've driven it for a day, you're going to feel naked without it," Team Penske's Power told a conference call.
"If you took it off, you'd feel pretty naked because there's not much protection there. So very happy that we're moving ahead with it," he added.
Power said he felt the aeroscreen will make drivers feel so much safer that it will prolong racing careers.
"I can remember a couple of times in the last five years on a super-speedway, there had been a big crash -- actually Scott's was one of them, and I actually went like that with my arm, not that that's going to stop anything, it's going to kill you," said the 38-year-old Australian, throwing him arm up as if to protect himself.
"But that's how much stuff you see flying towards your head and how lucky you really get, to get through all that stuff.
"Any time you're on a super-speedway and there's a big crash, it's just luck really to me. It's just a matter of time until someone got caught again. So yes, having a family and all that, you probably won't think about retiring quite so soon," he said.
Five-times NTT IndyCar Series champion Dixon, who tested a prototype on a simulator in July, said the aeroscreen made it a little awkward getting into the car and that drivers may want to allot more time when getting behind the wheel.
But both drivers felt the aeroscreen was seamless, and New Zealander Dixon of Chip Ganassi Racing called it "good to go."
"Ultimately it's just very quiet. I can hear my radio for a change. Normally I can't hear that. So that's kind of nice," said Dixon.
"But yeah, there's actually a lot less load on the helmet, too, so visually there's been really no impairment."
IndyCar has three more tests scheduled over the next five weeks, and aeroscreens are to be delivered to all NTT IndyCar Series teams before the end of the year and implemented for the 2020 season.
