During the 2021 season (and during others as well), we have had a number of situations where the safety car has affected the outcome of the race for various drivers in various ways. Fans on various sides have been angry about the results as we all know far too well.
I understand that the safety car is used to ensure the drivers are going slowly by an area where marshals are on track. This is exactly right - the marshals need to be protected from the hot heads driving the cars.
However, the safety car is a very blunt instrument for this purpose and ends up with the cars pottering around at unrealistic speeds, tyres cooling, etc.
Would it be better to use the "slow zone" concept as used at Le Mans, for example? Have slow zone boards and flags and between the slow zone starting flag and the green flag require the drivers to apply the pit lane speed limiter. No speeding and no overtaking in the zone.
That way, the cars are racing everywhere else on the lap and the risk of an incident like we saw at the end of the Abu Dhabi race is removed.
We then have a hierarchy of control - yellow flag: slow down, no overtaking; double yellows: slow down and prepare to stop, no overtaking; slow zone - apply speed limiter, prepare to stop, no overtaking; red flag - race suspended, return to pits.
No need for a safety car or a virtual safety car - the slow zone covers both of the situations that these currently cover - and we have more on-track racing, even during the recovery of a stopped car with marshals and heavy lift equipment on track.
