The 2017 title race was bubbling away nicely under the surface, until one moment at the Azerbaijan Grand Prix set the whole thing alight.
Sebastian Vettel and Lewis Hamilton were the two early-season front runners for the Formula 1 crown that year, and their rivalry really took off in Baku. They were both left pointing the finger at each other when Vettel hit into the back of Hamilton while they were trundling around behind a safety car.
It caused damage to both cars, as the Ferrari was left with a broken front wing while the rear diffuser on the Mercedes had also been affected. They had been first and second at the time, but by the end of the race it was Daniel Ricciardo in his Red Bull who took advantage of the chaos to win.
