Kamui Kobayashi is unsure there will be more overtaking during the 2011 season despite the return of KERS and the introduction of the moveable rear wings.
The Sauber driver reckons the fact that most teams will run KERS will mean its advantage is erased, and he is also unsure the current rules on moveable wings will make the system effective.
"I don't believe the KERS will help because almost everybody has it," said Kobayashi. "So it is only the rear wing and I'm not sure if the idea for the races of the one second gap to the car in front will really work."
Kobayashi, who became one of the stars of the 2010 season because of his overtaking moves, believes the skill to pass other cars will now be worth less.
"Maybe yes, especially in case it turns out overtaking really becomes much easier for everyone. But this is nothing to worry about because it is part of the rules," he added.
The Japanese also thinks those drivers who can manage all the new systems better will have an edge this season.
"The most important question is how you can improve laptimes with the new systems and by how much. I am working to get used to the new systems.
"It is a driver task and people who are using it well will have an advantage compared to those who are using it less efficiently. It is a matter of concentration, that is true. I can definitely manage that.
"Regarding all the talk - well, we are race drivers and complaining sometimes can be part of the business."
