The World Cup isn’t the only major sporting event to introduce video-assisted refereeing, better known as VAR, this year. The Tour de France, currently in its third and final week, is being officiated with the help of replay technology for the first time in its 105 year history.

In addition to footage from TV cameras, race officials—known in cycling as commissaires—are using another lens to judge the race: social media. Commissaires have access to an aggregator of several Twitter accounts which helps them identify and examine incidents as they occur on the road.
