The seven-time world champion was heard questioning Ferrari's tyre strategy, pit-stop timing, fuel calculations, weather forecasting and, briefly, the general concept of motorsport during Sunday's race.
“Why are we doing this?” Hamilton demanded over the radio.
There was silence.
“Why?” he repeated.
Still silence.
“Can someone tell me why?”
A Ferrari engineer eventually replied: “Because you told us to.”
According to sources, Hamilton immediately became “very upset”.
“Don't talk to me like that,” he reportedly responded.
Ferrari subsequently issued an internal memo reminding staff that radio communications should remain “professional, constructive and preferably one-way”.
Hamilton's radio complaints have become one of Formula 1's most anticipated forms of entertainment, with television viewers now reportedly paying less attention to the race itself and instead waiting for the moment Hamilton discovers that something has gone wrong.
“I can't believe this,” Hamilton was heard saying during qualifying.
Millions of viewers immediately leaned towards their televisions.
“What's happening?” asked one commentator.
Nobody knew.
“I'm just saying...” Hamilton continued.
At that point, bookmakers reportedly began offering odds on whether he would finish the sentence.

Ferrari has since installed a new “Hamilton Complaint Early Warning System”, consisting of a flashing red light in the pit wall that activates whenever Hamilton begins a sentence with “Guys...”
The system has already been triggered 47 times this season.
Engineers have reportedly been instructed to respond with one of three approved phrases:
“Understood, Lewis.”
“Copy.”
“We are looking into it.”
A fourth option, “You're absolutely right,” was removed after engineers discovered Hamilton would then spend the next seven laps explaining why they were right.
The situation reached crisis point when Hamilton reportedly complained that the car was “undriveable”, only to set the fastest lap.
“Lewis, you're currently fastest,” came the reply.
“I know,” Hamilton said.
“So...”
“But it shouldn't be.”
The engineer reportedly stared into the middle distance for several seconds before asking whether anyone had considered simply turning the radio off.
Ferrari team principal Fred Vasseur dismissed suggestions that Hamilton's radio behaviour was becoming a problem.
“It's fine,” he said. “We have accepted that Lewis is going to complain. It is part of the Ferrari experience.”
Asked whether the team planned to intervene, Vasseur shook his head.
“No. We tried once.”
“What happened?”
“Lewis complained about it.”
