Jul.6 (GMM) Bruno Senna has asked his critics to give him more time before writing him off.
"There is pressure that comes with my surname, plus people think this is my third year in Formula One, which it is not," he told the Sun when asked about his struggles in 2012.
Senna admitted some of the pundits' "bad comments" hurt him initially.
He argued: "This is the first time I have been in a competitive car with a proper structure behind me, so I am taking my time to learn it properly instead of trying to do everything all at once.
"I think people should look at me and make their judgement at the end of the season. If you look at a few of drivers, they were not as strong in their first year.
"But I am sure the second half of the season will be easier because I will have some experience of those tracks from last year, but it is a learning curve."
Some pundits believe that if Senna can not at least match his teammate Pastor Maldonado, who has won a race this year despite his own 'pay driver' label, he has no future on the grid.
"You want to win every race," Senna admitted, "but you need to be realistic. It is going to be tough to match Pastor, because he did a great job.
"But if I do well enough until the end of the season, then I will stay here."
