Felipe Massa has urged the FIA to look into the speed of formation laps after expressing frustration at Mercedes' conduct on Sunday.
The Williams driver endured a nightmare start to the British Grand Prix at Silverstone as an overheated clutch saw him stutter off the grid.
He was then caught up in a first-lap crash involving Ferrari's Kimi Raikkonen, forcing him to retire, and the Brazilian insists his initial clutch issues were the result of the slow nature of the formation lap.
With pole-sitter Nico Rosberg having led the lap, Massa urged the sport's governing body to look into the issue.
"I'm sure if you check, our formation lap in the last race (Austria) when we were in front was much quicker than the normal races," he is quoted as saying by Autosport.
"They [Mercedes] go slow for a reason, sometimes it's not good for the other teams.
"The FIA are saying we can't go so slow, but they are not penalising everybody.
"I stopped two times [at Silverstone]. I pulled the clutch, I was waiting.
"They are doing it for a reason. They [Merc] never say if they're going so slow, why?"
The issue of pace in the formation laps emerged earlier this year when race director Charlie Whiting is reported to have warned drivers as to the potential consequences of driving too slowly.comments
