I appreciate all the thought and research that IndyCar put into considering whether the windscreen would reduce the human element of this formerly open-cockpit racing series. No, I'm kidding... they didn't consider that at all.
Indycar's info is just a lot of technical details and more technical details. No consideration whether it removes the fan's connection to the human that steers the damn thing. No recognition that the drivers are there to entertain and serve the fans, including in dangerous circumstances.
So yea, Indycars will become fully-enclosed cars with little emasculated sunroofs.
I'll attend this year's Indycar race at the Texas superspeedway knowing it's the end of an era. You really do notice all the subtle human movements inside the cockpit, even at 200 mph and from dozens of rows up. I figure nobody in Indycar leadership has any recent experience from a fan's perspective like that.
