A "disappointed" Jos Verstappen believes his son Max needs to use his head and better control himself in the future after the Red Bull driver's clash with Sebastian Vettel in China.
The former F1 driver, speaking on Dutch TV's Ziggo Peptalk show, was unimpressed with his son's move on Vettel as the two were fighting for position on Sunday, and that better judgment was required.
"The overtake on Vettel really wasn’t on," said Jos Verstappen.
"That wasn’t possible. It was an error of judgment.
"In some circumstances Max just has to think more. I don’t want him to change his driving style. He passed two people at the start. He did that perfectly. That’s what we all want to see.
"But we don’t want to see these kinds of actions. He needs to have it under control. He needs to think.
"I’m seeing him tomorrow. Last weekend was very painful, but we’ll have to talk about it and analyse what happened in a normal way. This can’t happen. He already knows it, I don’t have to say much."
Jos conveyed his disappointment with his son's behaviour, but said he wasn't mad.
"Mad is not the right word, but I’m disappointed. But it’s more painful for himself," he said.
A veteran of 107 Grands Prix starts, Verstappen Snr. also gave his two cents on Max's on-track encounter with Lewis Hamiton in Bahrain, a week before Shanghai, but in that instance labeled the run-in a racing incident.
"I don’t think there was anything wrong with that, I still think it was a good move," he added.
"Afterwards you could say Max should have given Hamilton more room, but Hamilton could have done the same to Max. That’s why it’s a racing incident and they’re both taking the blame.
"He did it really well. He has to take more risks with his Red Bull because the top speed is lower than the Mercedes."
Jos also took issue with the press, insisting his son has come under intense but unfair scrutiny from the media.
"Max is being put under the magnifying glass, also because of his age," he said.
"If you look at the last race in China, then Alonso pushed Vettel wide, and not just a little bit. And that’s not being talked about.
"Max did that to a lesser degree and that’s all people talk about. At least he let Hamilton live. Max is being butchered by the press and I don’t think that’s correct."
