Teams have backed up the idea for sprint races before the Grand Prix. It basically means that there will be no second or third practice. Qualifying, which will now take place after first practice, will now determine your placement on the sprint race. Which is approx 100km. The top winners of the sprint would earn half the points on the Grand Prix. Respectively filling the grid in the order the sprint finished.
Conceptually, is a good, not great idea. Gives the smaller teams a chance to score points. But my biggest issue is the sprint on a course like Monaco, where it is virtually impossible to overtake. That plus vehicles breaking and having to replace parts that can mean getting a penalty.
