F1 faces safety concerns and confusion at Australian GP.

Mercedes team principal Toto Wolff has called for Formula 1 to better define when to use red flags during races. The recent Melbourne GP was dominated by three in-race red flags, leading to lengthy delays and chaotic standing restarts, which eliminated several drivers. Wolff thinks F1 needs to do a better job defining when a race must be stopped and when a physical or virtual safety car is enough to clear an incident safely. He suggested defining what is a VSC, what is a safety car and what is a red flag.
