Indeed. Also who can forget the insane Brabham BT46B also known as the 'fan car'. Everytime I hear how ugly halo is that is the first thing I think of in the ugly stakes.

With regard to how the final halo will look, if those drawings from Hass and Mercedes are correct then the final look of different teams halos will vary somewhat. As a technical forum the differing design concepts should create plenty of discussion on here and I for one am looking forward (in a weird way) to see what they have come up with.

slow, sure.

A shame the Lola Mastercard didn't work. It was atleast a step further than USF1 racing team.
as for HRT? They lasted longer than expected to be honest.

as for their finishes?

some interesting facts here.

2017 McLaren F1 team: out of 20 races, there were 18 DNF's.
vs
2011 HRT F1 team: out of 19 races, there were 11 DNF's.

matter of fact, HRT has never had as much DNF's as Mclaren had in 2017.
yes, net result had Mclaren achieve points and HRT never.

but by all comparisons, Mclaren was a bigger disgrace in 2017 than HRT ever was concidering the budget, resources and knowledge.

does the halo look ugly at this point? sure.
can it look better fast? definately.

Image

want ugly?

the halo is nothing in comparison to all the above. does it negatively effect f1 aesthetics? sure.

but i fail to see how HRT and Lola can be called a disgrace in comparison to the HALO.
the halo is a reasonable result from advancing safety in motorsport.
HRT and LOLA's lack of performance was due to a lack of funding in a world where spending is out of all sorts of control.

and again, despite Mclaren atleast achieving some points at the year's end, HRT actually ended up with less DNFs despite having not even the slightest amount of funding in ever-changing situations like bankrupcy, new owners, base moving, all from starting when campos meta pulled the plug fast because the promised budget cieling never happenend.

I dont mind the look of the exposed tubing personally, looks like an old split pane windshield. Slap a sheet of lexan on it and you have an aeroscreen as well.

as for the people here that are missing some history book information , aeroscreens/windscreens/halo-ish devices again are nothing new

I'm guessing the slot in the screen on the later pics was to make up for the visual distortion.

I would think it's more about forming technique used/available at the time. You can see the plastic is fairly cloudy which I would suggest is from overheating ahead of vacuum moulding. Having made that sort of screen before I can attest to it being tricky to get the temperature right for pliability, without melting the acrylic.

also drivers back then where hard as nails and it would have been seen as soft to not allow themselves to be hit in the face by small objects :D :D :D :D

Interestingly, as the pic with the early F1 McLaren (to the left of the red car in M2u's pix set, 3rd from bottom) reveals, some thoughtful effort was made by McLaren over a few years - to use a functional aero-screen.

This is more semi-transparent bodywork. The drivers head sticks out quite a lot over the green tinted screen (just look at the headrest)

That is a matter of seating position/posture, & the driver view/visibility factor was evidently a needful aspect, as it is today.
