Team Lotus' Jarno Trulli has taken a swipe at the race stewards at Sunday's Hungarian GP after they failed to penalise Sergio Perez.
The Italian claims that the Sauber driver jumped a chicane early in the race while the pair where dueling for position but the Mexican received no punishment for the apparent infraction.
While the incident had no real baring on Trulli's race as he was forced to retire with a hydraulics problem after only 17 laps, he still took the stewards to task over the matter.
"This time around it's my turn to complain and tell the FIA off, despite my race ending almost immediately," Trulli wrote in the Repubblica.
"At the start I already had to deal with three incidents ahead of me that pushed me to the back, then Perez arrived with his absurd behaviour and everything was over.
"He was strangely slow, more than my Lotus: I overtook him twice and to regain his position he cut the chicane. The rulebook is crystal clear, he had to move over and give the position back to me; instead he didn't care, he stayed ahead of me.
"He showed a rare kind of rudeness and a unique ignorance of the rules, but I wonder why the FIA did not take any measure. What is it there for? What was it looking at? I understand why a boy would shrug, but the stewards had to intervene.
"I could overtake him only in the slow sector but didn't manage to anymore, he slowed me down and ruined my race before my engine threw a tantrum like at Silverstone and forced me to retire.
"My message is clear: there is only one rulebook and it's the same for everyone: not just for the guys ahead, but also for the people at the back of the grid."
