Jarno Trulli should vacate his seat completely if he is no longer enjoying Formula One.
That is the view of the veteran Italian's contemporary David Coulthard, who today travels to the Grands Prix as a consultant to Red Bull and commentator for British television.
Team Lotus boss Tony Fernandes this weekend admitted Trulli, 37, had been "extremely accommodating" in agreeing to step aside for the Nurburgring weekend so that Karun Chandhok can have a full weekend in the car.
It is suggested that Trulli is happy to wait until Hungary for a new power steering system and in order to guarantee a contract for 2012, but Scot Coulthard said the Italian should consider whether he is still enjoying the sport.
"I don't see his results, and by extension his motivation, improving significantly from this season to next."
