So much for Lewis Hamilton and Sebastian Vettel's 'friendly' 2017 title rivalry…
In an Azerbaijan GP of astonishing incident and controversy, championship leader Vettel was punished for driving into Hamilton's Mercedes in the season's most dramatic moment so far.
Running at the front of an increasingly chaotic Baku race just as a second Safety Car period was ending, Vettel hit Hamilton's Mercedes up the back at Turn 15 before the Briton had accelerated fully onto the long main straight.
Then, in a clear show of anger and frustration, Vettel, waving his hand in the cockpit, pulled up alongside the Mercedes and turned right straight into Hamilton's left-front wheel.
Stewards put the incident under investigation and found Vettel at fault for 'dangerous driving', giving the Ferrari driver a 10-second stop-and-go penalty.
Vettel had complained over the radio that Hamilton "brake tested" him in the first incident, but the second earned an immediate rebuke from Sky F1's pundits.
"That's a rush of blood to the head and he should have more self-control in my view," said former world champion Damon Hill of Vettel.
Watch the incidents above between F1 2017's top two above and judge for yourselves!
