Red Bull's chief technical officer Adrian Newey is still caught in two minds over the implementation of the Halo, praising the safety element but critical of the design.
The Halo will be fitted to all cars from the 2018 season onwards, much to the annoyance of many drivers, teams and fans alike.
The aesthetics of the Halo is the main gripe, but teams have been up against time trying to develop the cockpit safety device as part of their design plans for their 2018 challengers.
And while Newey believes driver safety does need to be improved, he is not convinced that the Halo is the way to do it.
"I have to admit I do have mixed feelings on the Halo," Newey told Sky Sports F1.
"On the one hand, I do feel that anything you can do to make a car safer is a good thing.
"When somebody gets' really seriously injured or dies that it is horrific. I attended Justin Wilson's funeral three years ago, and to see the grief on the family's faces was terrible.
"So if it helps to make the car safer, that has to be applauded.
"The engineer in me says that it just seems to be such a clumsy and ugly solution, it just feels as if we ought to be able to do something better than that."
Newey feels more time and development should have gone into the whole process in order to come up with a decent solution that can be implemented all levels.
"I think there needs to be more research," he added.
"Probably a canopy would be visually more attractive, but then it's closed-cockpit racing.
"What is important is whatever Formula 1 does has to be affordable for the lower formulae, because the bottom line is why should a Formula Ford driver's life be valued less than an F1 drivers' life?
"We have to find a solution that can be carried across, but there's no escaping it's ugly. The aesthetic artist in me finds that offensive."
