The Times has learned from sources among the F3 teams that the reason this year’s event was canceled was the mandatory 14-day quarantine measures being enforced by the local government for all non-Chinese nationals.
The sources, which requested to remain anonymous, said “there was willingness for the majority of the teams to come to Macau,” which clashed with the “inflexible approach” of Macau authorities.
According to the teams, the event would be able to run if team members could present a valid negative nucleic acid test for Covid-19 and enter Macau. This would be followed by a “travel bubble” established between the circuit and the lodging facility, similarly to what happened during the season in Europe, which came to an end yesterday with Australian driver Oscar Piastri from Prema Team winning the championship title.
=================================================
It is the Macau govt who do not want to risk hosting the F3 race because they are worried that the "Travel Bubble" won't work.
