Would just like to point out how he lets go of the wheel with both hands to grab his face because his visor was up. Lucky the car went little left on to the grass and not right into the path of on coming cars.
I do not understand how people can drive with the visors up or with open faced helmets. I have been hit by rocks in the face with my visor up just driving around an autoX course with new r-comps, there is no way I would be driving at the speed with it up I dont care how hot it is. Eyes > discomfort.
I am guilty of driving with my visor up in the car, with the hardtop on. I find with the visor down my breath fogs it in the car at low speeds. I have tried closing the visor just before green flag for the session, and while that works during the session, the visor starts to fog rolling back to the paddock, and I can't raise it one handed. I am always wearing my sunglasses, which while not as good as the visor, at least offer some impact protection.
In open air, like in a kart, that's not a problem. Perhaps not with the top down at an autox either.
Well I'd say it depends on the track. PIR here in Portland doesn't have any deer or other large animal issues that I'm aware of. ORP doesn't either - you can literally see for 10 miles in every direction. There's a reason the town is called "Grass Valley". A lot of people run open face helmets.
