I guess I ended the video to early.... I did not see it pacing any other cars
Sorry tool fan, but I gotta pull a nerd move and quite Wikipedia.
Under "Safety Car":
"In motorsport, a safety car or pace car is a car which limits the speed of competing cars on a racetrack in the case of a caution period such as a major accident or obstruction on the track. "
"In Formula One or other road racing events if an accident or
heavy rain prevents normal racing from continuing safely, the Race Director or Clerk of Course will call for the marshalls to wave yellow flags and hold SC boards, warning drivers that the safety car has been deployed."
