Lewis Hamilton and Sebastian Vettel escaped with official reprimands but no actual penalties after their pitlane incident during the Chinese grand prix.
Stewards, including former F1 driver Alex Wurz, deliberated the incident after the 56-year-old race.
Hamilton attempted to race the German both on the pit entry and exit, and Vettel moved over on the Briton in the pitlane.
In separate stewards reports, the officials said Hamilton and Vettel drove "in a dangerous manner" and were issued the "penalty of a reprimand".
McLaren’s Hamilton said in the post-race press conference on Sunday that he was not aware the incident was being investigated.
"As far as I am concerned I think it was okay. We touched wheels but otherwise I think it was fair," said the 25-year-old. "It was good racing."
Vettel, however, was upset with Hamilton’s driving.
"I don’t know why he was keen to touch me," said the Red Bull driver.
