That rule makes it nearly impossible for the Formula 1 circus to move that way after the Austrian Grand Prix, because then racing will be at a standstill again for at least two weeks, while it now wants to overtake as many races as possible.
F1 bosses continued to talk to the highest levels of Government on Tuesday in the hope of brokering an 11th-hour agreement to win the sport an exemption over controversial plans to impose a 14-day quarantine period on travellers arriving in the UK.
The race at Silverstone in July is still scheduled to go ahead despite the opening 10 races of the Formula One season being cancelled due to the coronavirus pandemic.

China should actively participate in the work of independent review of the WHO's COVID-19 response, the Commission added. The probe is expected to shed light on the origins of the virus and China's early handling of the outbreak.
"A 14 day quarantine would make it impossible to have a British Grand Prix this year", an F1 spokesperson said.
"It has a major impact on literally tens of thousands of jobs linked to F1 and the supply chains".
"We would be travelling back to the United Kingdom on F1-only occupied aircraft and all staff would be tested making a quarantine totally unnecessary. If all elite sport is to return to TV, then exemptions must be provided".

Seven of the 10 teams on the Formula One grid have bases in the UK.
Despite high-level lobbying from F1, which is understood to include direct representation to prime minister Boris Johnson, it is understood the government will not exempt any sport.
F1 organisers are hoping to start the season with the Austrian Grand Prix on July 5 behind closed doors, followed by a second race at the Red Bull Ring a week later.
"Grossly incompetent" Trump dismisses Obama over second Covid-19 criticism
Unfortunately, a lot of so-called grownups, including some with fancy titles and important jobs, still think that way. Trump's reaction came after Obama on Saturday criticised the USA authorities' response to the coronavirus outbreak.
Should the government confirm such a policy, this immediately places in jeopardy the two races at Silverstone that are due to take place at the end of July/start of August.
