1967. The Ice Bowl.

From Wikipedia

“The Ice Bowl”

The game became known as the Ice Bowl because of the brutally cold conditions. The game-time temperature at Lambeau Field was about −15 °F (−26 °C), with an average wind chill around −48 °F (−44 °C); under the revised National Weather Service wind chill index implemented in 2001, the average wind chill would have been −36 °F (−38 °C).[32] Lambeau Field’s turf-heating system malfunctioned, and when the tarpaulin was removed from the field before the game, it left moisture on the field. The field began to freeze gradually in the extreme cold, leaving an icy surface that became worse as more and more of the field fell into the shadow of the stadium.[33] The heating system, made by General Electric, cost $80,000 and was bought from the nephew of George Halas, George S. Halas.[citation needed] On the sidelines before the game, some Dallas players believed that Lombardi had purposely removed power to the heating coils.[34] The heating system would eventually be given the moniker Lombardi’s Folly.[35] The prior convention to prevent the football field from icing up was to cover the field with hay.[36]
The Wisconsin State University–La Crosse (now the University of Wisconsin–La Crosse) Marching Chiefs band was scheduled to perform the pre-game and half-time shows. However, during warm-ups in the brutal cold, the woodwind instruments froze and would not play; the mouthpieces of brass instruments got stuck to the players’ lips; and seven members of the band were transported to local hospitals for hypothermia. The band’s further performances were canceled for the day. Packer linebacker Dave Robinson recalled that the field did not get really bad until the second half, saying that since the halftime show was canceled there was no traffic on the field for an extended period to keep the surface crust broken up. During the game, an elderly spectator in the stands died from exposure.[37]
Prior to the game, many of the Green Bay players were unable to start their cars in the freezing weather, forcing them to make alternate travel arrangements to make it to the stadium on time. Linebacker Dave Robinson had to flag down a random passing motorist for a ride. The officials for the game found they did not have sufficient clothing for the cold, and had to make an early trip to a sporting goods store for earmuffs, heavy gloves, and thermal underwear.[38] Packers quarterback Bart Starr attended an early church service with his father, who had visited for the game, and as Starr later said, “It was so cold that neither of us talked about it. Nobody wanted to bring it up.”
The officials were unable to use their whistles after the opening kick-off. As referee Norm Schachter blew his metal whistle to signal the start of play, it froze to his lips. As he attempted to free the whistle from his lips, the skin ripped off and his lips began to bleed. The conditions were so hostile that instead of forming a scab, the blood simply froze to his lip. For the rest of the game, the officials used voice commands and calls to end plays and officiate the game. Nothing was immune from the cold; at one point during the game, CBS commentator Frank Gifford remarked, “I’m going to take a bite of my coffee,” as it too had frozen in the mug.[39]

It doesn’t have to be as cold as 40°F for an English car to fail starting. Sure, Lucas introduced the intermittent wipers, but they also introduced the intermittent lights, intermittent alternator, and intermittent starters to the world too! Also they showed that electricity isn’t conducted through wire but through the smoke in the wires. If it leaks out, then it fails.
