I thought the Safety car was there for the "Safety" of Marshals etc on track?
With the current regs you would get the Safety car followed by a train of cars all travelling at a speed dictated by the safety car.
The new regs would spread the cars out and have backmarkers racing found to rejoin the back of the train losing out on the control of the pack and the "Safety"
Doesn't really make alot of sense to me, maybe they should just call it "The car"
I may of course be wrong, it has happened before
