Australian Grand Prix boss Ron Walker has said most F1 drivers are prima donnas.
Reacting to criticism that this year's race ran too late, and that the falling sun led to dangerously dark conditions, Walker said: "It's clearly not dangerous.
"You can't please these drivers, they are a bunch of lazy people who won't do anything to help the sport, except for two or three.
"A lot of drivers are prima donnas. They are never happy," he added.
