Toro Rosso's Daniil Kvyat says the amount of track knowledge held by F1 teams now makes running on Friday's practically dispensable.
The case for reducing the Grand Prix weekend format by concentrating the action over two days instead of three is gaining momentum among the teams, especially in light of a potential expansion of the F1 calendar.
But regardless if Liberty Media increases the number of races in the future, Kvyat argues that Friday practice sessions are already non-essential in his view.
"Maybe we need to just come on the track on Saturday," said the Russian.
"That's it. Honestly we are so up [in terms of knowledge] on all the tracks we know.
"I think we need to allow extra time on new tracks, like it's going to be Vietnam or something, maybe, but I don't know.
"It's up to F1 people to decide, what is best and what is not. Every driver is different. Someone needs maybe five hours. But not me."
Red Bull team boss Christian Horner is on te same page as Kvyat, pointing to Friday's truncated running in Azerbaijan as proof that the schedule could be reduced to include just one free practice session.
"I think that depends on how many races we end up with. If we end up with more races, then arguably we do need to condense the time," Horner said.
"We saw one session worked well enough on Friday here. Maybe one good session is the way to go. Then parts and people could turn up a little bit later.
"One session is enough for the weekend."
