Somewhat of an extreme example there man, lol. Not your every day usage.I used to drive my 1979 Mustang V6 in -30°F in North Dakota. I had a 100 mile round trip for work. Even with the grill blocked off it never got hit enough to clear the inside of the windshield. Oddly, whenever it was in the 35°F-40°F range with high humidity, the carburetor would ice up.
