Manufacturers call it a "needle sweep" you can probablt turn it on/off in the menus, or via an OBD-II cable.

Often a test mode. On one car I had with a manual button to reset the trip mileage meter holding down the button when starting the car put the dash into the test mode where the speedo and rev counter needles first did a a full traverse of the dial.
