The pit crew has one job. Well, actually, they have a ton of jobs. But the point is to get all of those jobs done extremely fast so the racer can get back out onto the track. While there a been quite a few pit stops in F1 this season, this is the fastest. At the Canadian GP the Williams team (with driver Stroll) accomplished a lightning fast pit lasting a mere 2.17 seconds. Check out the video of it below.
