Max Verstappen and Lewis Hamilton's furious battle for the 2021 drivers' championship title comes down to the final race in Abu Dhabi on Sunday with both drivers level on points.
It is only the second time in Formula One history that the top two in the standings go into the finale equal on points.
It was 1974 the last time such a feat occurred, with Emerson Fittipaldi and Clay Regazzoni all-square, before Fittipaldi took the title.
But the Verstappen and Hamilton row, one of the most bitter rivalries in the history of the sport, is better compared to Alain Prost and Ayrton Senna, and in particular their championship-deciding collision back at Suzuka, Japan, in 1989.

Senna's eyes were fixed on Suzuka and Adelaide, the final two races of the 1989 season, and he knew he needed to win both to defeat his Honda-McLaren team-mate and win the title.
The hatred between them and the ruthlessness of the battles on track are like little fans have seen until this season with Verstappen and Hamilton uncompromising in their fight for glory.
A question on the lips of F1 fans in the hours since the chaos in Jeddah is: will Verstappen torpedo Hamilton to seal a maiden world title?
Verstappen, although level on 369.5 points, is ahead as he has more race wins (9) than Hamilton (8). Could he look at Prost-Senna and put everything on the line to take out a rival? Mercedes team principal Toto Wolff, when speaking to Sportsmail recently, felt it was an option both title-chasing drivers could go for.
That belief has its roots in one of the most famous collisions in the history of F1 - and the warnings it should send to Verstappen and Hamilton if they are considering repeating the trick.
Having taken pole position by an impressive 1.7 seconds over his team-mate, Senna was 'charged up like a Duracell,' wrote Autosport from trackside at Suzuka.
Senna, the 1988 champion, had clawed his way back into the championship race and while he knew he was considerably worse off in pure straightline speed - something Verstappen is having to concede to Hamilton - his opportunity was always going to come on the corners.
The brief was clear for Senna, he had to win the remaining two races. One more DNF would extinguish his hopes of retaining his title. For Prost, he knew he had to do everything in his power to keep Senna behind him.
'All I can do today is attack, attack, attack,' Prost told reporters on the morning of the race.
'There's nothing else for it: Senna has to win to keep a chance of the championship, and the best way to stop him is to beat him. Second place won't help either of us.

The moment Senna got a push back into the race from the track marshalls at Suzuka
'In the past, you know, I've left the door open for him sometimes - otherwise we would have crashed; I won't be doing that today.'
The last line was the stand-out, the headline, the attention-grabber. No doors were going to be opened - if anything, the Frenchman was ready to slam one in his rival's face.
Prost made the better getaway and while others like Nigel Mansell had hopes of upsetting the apple-cart, it soon became clear this was McLaren v McLaren, alpha v alpha, both pushing the other to the absolute limit.
It was Prost who roared off into the distance, at one stage building up a lead of five seconds, but as he had done in the weeks leading up to Suzuka, Senna masterfully reeled his most hated rival back to within touching distance.
Pit-stops swapped the lead temporarily; Prost came in first, soon followed by Senna, and from there it was a fight to the finish - until lap 47 changed everything.
Senna knew overtaking options were severely limited to him given the
