I have only driven my car twice and about 50 miles to date.
I'm wearing a pair of Harley biker glasses with the poly chromatic lenses (lighten & darken in the sun) and the sponge gasket around the edge, to keep the wind out of your eyes.
Ear plugs.
A sort of Flying helmet.
Body warmer and bomber jacket.
Seems to keep me warn enough, but there is a fair draught around the feet, I can see a fair bit of daylight up in the foot well.
