Re: deer comment. I'm not able to search YouTube at the moment, but someone can find the Corvette that collected a deer in the windshield during a track day (with his helmet visor open) and shielded his eyes from the glass with his hand.
I keep my visor down at all times in the car now, and I wouldn't run an open faced helmet without feeling sketchy.
