Efforts to improve cockpit safety have ramped up since Justin Wilson was killed by flying debris in an Indycar race in 2015.
While Formula 1 has taken the matter into its own hands with the development of the 'Halo' safety device which could be introduced as early as next year, Indycar has said that it will not put the 'Halo' up for consideration.
"We don't see that - the Halo - having any possibility for us," said Mark Miles, CEO of Indycar's parent company.
"We have banked tracks and you can't see out of the car with that. But we are very interested in developing driver head protection and continue to work hard."
Miles said that Indycar would more likely investigate a 'aero screen ' approach close to the canopy concept tested by Red Bull.
"We are more likely to introduce a limited windscreen rather than that Halo."
While the 'Halo' appears to have a preference with the majority of F1 drivers, the FIA insists that an aero screen safety device is still under consideration.
"Technically it is possible," said F1 deputy director Laurent Mekies.
"We are currently waiting for the final decision about Halo, and whether they want the cockpit cover or something in between which is more aesthetically appealing."
