Max Mosley has expressed concern over the length of the 2011 calendar which, for the first time will feature 20 races.
The former FIA-President believes fans will become tired by continually dedicating their Sundays to the sport.
“For me, personally, [20 races] is too much,” he told German newspaper Welt. “In my honest opinion it will be too many Sunday’s for the fans who will have to adjust their Sunday afternoons to fit with the sport. At some point it becomes a nuisance.”
The 70-year-old also reckons that fans might opt to miss a race weekend, which can create a snowball effect, damaging the sports TV audiences.
“If you start to skip a race, that can quickly become a habit and, when it comes to the TV ratings it leads to a snowball effect,” he added.
