Why?
If a driver has tested positive, then according to UK Test & Trace guidelines, anyone who they have come in close contact with should self isolate (at home) for 14 days. A bit tricky if, like most of the marshals at Silverstone, they are a considerable distance from home.
I would have thought that anyone approaching the car/driver should be warned of that fact and can make choices as to what they will do, hopefully that will avoid them consequently having to self isolate.
Having read through the details on the links in the opening post, there does, as usual, seem to be a lack of details as to how the FIA/Liberty plan to handle the marshalling aspect.
All I could really find was that 'marshals will operate in small family groups' so as to avoid unnecessary interaction with others.If marshals do have to self isolate, will the organisers have a supply of substitute marshals available to replace them, and how does that fit with the 'family group' concept.
As an aside, I had a phone conversation this afternoon with an ex marshalling colleague with many years experience including at GP level.
We both agreed that we are glad we are out of it, though he said that he had recently had a letter from someone high up in the marshalling world, asking if he was considering coming out of retirement, even though he has not done any for six years.
Maybe an indication that there may be some problems getting marshals for this season - have heard anecdotal evidence that many older marshals are considering this to be a good point to 'hang up the Probans'.
Look I know marshals are important and you make a lot of good points about them, but this argument really isn't about them - if a driver tests positive he obviously shouldn't be allowed anywhere near the race track and should be taken out of the paddock immediately not to infect anyone else, be it marshals or his team members or anyone he interacts with. Plus odds are he's not in brilliant shape to race.
