It's honestly really screwed up if a country just closes its borders or stop flights from entering in a matter of hours. Imagine if, for example, teams are heading to Albania (currently 0 cases) and your flight gets cancelled or redirected. Or all teams are already in Albania and you have problems heading for another country. Or worse, imagine if some teams are forced to be quarantined and the whole season is canned for this year.
I assume everyone's mentally prepared for to this to stretch beyond the typical 21-25 days.
Perhaps the route will feature more countries in Africa, the Pacific and Latin America (but of course, in countries wih adequate healthcare systems). I suppose we will see more countries with double legs, just like TARAUS4.
