Homolgated FIA approved isoltion cells. All drivers and team members must use these at least two weeks before any event. The cells are one per person and are chambered like a pea pod or the womb of a sow (take your pick) so that multiple cells are umbilicially connected to a shipping container.
Oxygen, water, food, wastes are transported in the umblicials. While blood quality, stool, breath and other phsyiological parameters and vital signs are monitored. The cell passenger may opt to go into semi-cryo sleep/suspended animation/induced coma to speed the flow of time before the race.
If any Corona Virus is detected the cell raises an alarm and the cell is tranported to a Hospital hub for treatment.
If all vital signs and serology is clear the cell is green lighted and the isolation container passport is stamped for sbipment to tbe race. Race briefings are viwed in the "Augmented reality lenses" while in the cell. otherwise Briefings are uplinked directly to the brain for those passengers in Cryo-sleep. For muscle memory conditioning, electronic impulses are sent to the muscles to violently trigger them with car controls and G-force data streams as if the driver were doing two race distances.
The cell passengers are never exposed physically to anyone else before, during or after the race. He must wear is aspirated full body cell membrane aka "X-Placenta". The slimy gleam around the drivers will look a little off-putting at first - goes without saying he must avoid sharp objects! - but these measures are all but necessary to maintain total isolation through the races this season.
PS.. This is a creative view of how Covid-19 could affect things.. If it goes on longer than we like.
