Four-time world champion Sebastian Vettel on Friday cautioned against the temptation to shoehorn too many Formula One races into a revised calendar, describing the move as "not realistic".
The 22-event F1 season has been decimated by the coronavirus with nine races either cancelled or postponed.
The French Grand Prix scheduled for June 28 is also in doubt as is the Belgian Grand Prix, set for August 30.
F1 chiefs have floated the idea of making up for lost time by staging races on successive weekends or even having two races on the same weekend.
However, Ferrari star Vettel fears such a move could lead to burnout for team staff.
"We drivers are a little privileged," Vettel told reporters by teleconference from his home in Switzerland.
"Of course, the races are tiring but there have to be limits for the staff. They must rest.
"We must also see if it is easy to reschedule races, if the circuits are not already taken. Many questions remain. I think the schedule will be busier, but 10 consecutive weekends is not realistic."
