Lewis Hamilton needed to finish fifth or higher at the Mexican Grand Prix on Sunday to win the Drivers' Championship.
Heading into the race, the Stevenage-born driver was 66 points ahead of Sebastian Vettel - who needed second or higher - and cruising to a fourth title.
But within 30 seconds of the race, disaster struck. Hamilton and Vettel clashed, with Vettel's front wing damaged and Hamilton's back-right tyre punctured.
Hamilton was forced to drive the remainder of the lap at half speed before going into the pits, meaning he came back out in dead last.
The 32-year-old fought his way back into the race and while he only finished ninth, Vettel only managed fourth, meaning he won his fourth title.
A lot will be made of his coming together with Vettel, in terms of who was at fault and whether Vettel intentionally drove into Hamilton, aware that he needed a result.
Hamilton will undoubtedly be annoyed about the incident and demand to see replays when he gets the chance. Check out a video below at 0:27.
F1 fans, however, were not sharing his pain at the time of the accident.
When Hamilton re-emerged from the pits, he said something to Mercedes' team on the radio that saw him slammed by viewers.
He said: "Did he (Vettel) hit me deliberately?"
Still seething from having his tyre punctured, Hamilton wanted to find out whether Vettel drove into him on purpose. His team replied: "Not sure, Lewis."
But there are a couple of things wrong with that, because why would Vettel risk his own race just to get Hamilton? Well, you'd like to think he wouldn't seeing as he needed to finish second.
That's what F1 fans were saying anyway, as you can see in the Twitter reaction below.
