The former world champion was busy in the world rally series last year when formula one introduced the moveable rear wing system, designed to boost overtaking.
Having skipped the 2010 season entirely on television, Raikkonen began to watch some grands prix last year when his thirst for circuit racing returned.
“The way the DRS wings work is for me a little ridiculous,” he admitted to Germany’s Auto Motor und Sport. “Overtaking is not really a great art anymore.
“You just put the wing down and go past easily,” said the 32-year-old. “The guy in front can’t really do anything.
“But I agree that at least it makes the show better,” added Raikkonen.
He admitted that his brief stint in American Nascar racing last year rekindled his love for wheel-to-wheel.
“I realised how much I was missing it,” said the former McLaren and Ferrari driver. “That doesn’t mean I am sick of rallying; actually I’d like to do both but that’s not possible.
“But if you want to race and you have the choice, first you look at formula one,” he added.
Raikkonen was the fastest of all when 2012 testing kicked off at Jerez on Tuesday, insisting he is not fazed at the prospect of returning after two years away.
“For me it’s easier to get used to the (Pirelli) tyres than it was for the others a year ago. For me it’s more like a new beginning.”
As for the refuelling ban, which came in last year, Raikkonen insists: “That’s no big deal — the pitstop is just a little shorter.
“Driving with the heavier car is not like day and night; it’s still the same sport. There’s just a few more buttons to push on the steering wheel.”
