When running deliveries in the snow one morning I was trying to pass a semi, which was causing white out conditions. No joke, I navigated using the driver side wheels and the rumble strip on the side of the interstate at 70 mphIf you can't see while you are driving, you can stick your head out the window and listen for the sound of your tyres scraping against the curbs to steer.
Or so I am told.
Absolutely clear vision once I got around it
