Sergio Perez is adamant his collision with Romain Grosjean at Sepang was a racing incident and did not warrant a penalty.
Fighting for position with the Lotus driver, Perez tagged Grosjean and put him into a high-speed spin.
Grosjean, naturally, was unhappy about the incident and complained to his team while minutes later the stewards launched an investigation.
The outcome of that was a 10-second stop-go for the Mexican driver, who finished down in 13th place.
"The penalty didn't help us; I felt I had nowhere to go and couldn't avoid contact with Romain," he revealed.
"I thought it was a racing incident but it ended up costing us a lot."
As for the rest of his Sunday in Malaysia, Perez says tyre degradation also played a role in his lack of points.
"We knew ahead of the race it would be a big fight to get close to the points and it turned out to be just the case.
"I struggled with degradation in my first stint, on mediums, and that cost me a lot of time after the Safety Car.
"We had slightly better pace with the hard compound, but in the end it was not enough to get back in contention.
"It's a disappointing result but at least we were able to learn a lot from this race and this will help us going forward."
