As Lewis Hamilton cruised to victory in Abu Dhabi on Sunday, it would be fair to wonder why he would ever contemplate the prospect of racing for a new team.
The Mercedes driver led from start to finish, recorded the fastest lap and won by a gap of over 16 seconds to Red Bull's Max Verstappen.
It was his 11th victory of 2019, matching his personal best total in a season, and was a win that came with his sixth Formula 1® drivers' title long since secured.
The final gap in the title race was a massive 87 points over team-mate Valtteri Bottas, with Verstappen, the closest driver from an opposing team, ending up out of sight at 135 adrift.
Mercedes made an emphatic start with eight straight wins and while they were challenged by Ferrari and Red Bull in the middle of the campaign, they recovered to win five of the last six.
Hamilton was in a class of his own on race days, especially considering the pole he claimed at Yas Marina Circuit – a traditionally strong track for Mercedes – was his first in 10 races.
He goes into 2020, the final year of his current contract, as the clear favourite to triumph once more, with Michael Schumacher's record of seven titles now tantalisingly close.
Hamilton is loved by Mercedes, has the best car and a team-mate in Bottas who, unlike his spell alongside Nico Rosberg, has steered clear of controversy and would struggle to beat him over a 22-race slate.
What a way to end the season. I’m so grateful to my team @MercedesAMGF1 for the hard work they have put in this year, constantly raising the bar. But above all, thank you #TeamLH for your support. The positivity you give me is overwhelming. I feel your love all around the world. pic.twitter.com/Yaf4cCYlmi

Why then is the possibility of a move to Ferrari in 2021 even on the agenda? The next contract Hamilton signs could be his last and it is one that may prove legacy-defining.
He is 34 but eager to continue for a few seasons yet, leading the sport into its new era of technical regulations, which come into play the year after next.
Hamilton's talent and achievements have not always been properly appreciated, nor his mental strength and competitiveness that often lifts him above rivals.
He has been booed by Ferrari supporters, while his personality has not always proved endearing to prospective admirers.
Earlier this year, Toto Wolff expressed his surprise that Hamilton is not more revered in his home country, the United Kingdom, in comparison to other sporting greats.
It is one of many factors that must make joining Ferrari, the sport's most popular team, tempting.
Ahead of the season-ending race in Abu Dhabi, Mattia Binotto openly discussed his happiness at the possible availability of Hamilton.
Hamilton has repeatedly said he wants to see what close confidant Wolff does before deciding on his own future and explained after Sunday's win he would think about his options.

Asked about rumours he met with Ferrari president John Elkann, Hamilton said: "Everything that happens behind closed doors is obviously always private.
"But I think for many, many years, I've never, ever sat down and considered other options, because we've been just driving straight ahead into the path and journey that we've been on.
"It's only smart and wise for me to sit and think of what I want if it is the last period in my career. I want to keep winning and being able to fight with these guys. I can't really tell you what else is going to happen moving forward."
With Sebastian Vettel's performances showing signs of decline, it is Charles Leclerc, Ferrari's rising star, who would likely be Hamilton's team-mate.
Leclerc said after the race he would welcome the challenge of having Hamilton in the same team, a move which could mean Verstappen – the other man set to lead F1®'s next generation – could fulfil his mooted move to Mercedes as their new number one.
Verstappen could alternatively continue to lead Red Bull if they show sufficient progress next year, but either way, the 2021 grid would be a fascinating picture, with Alex Albon, Lando Norris and George Russell the other young stars in the mix for top drives.
It remains the most likely scenario that Hamilton remains with Mercedes and helps them to extend their unprecedented run of six consecutive driver and constructor doubles. He added to his comments on Ferrari by saying he still loves life with the team.

It would undoubtedly be a risk to leave that comfort and winning culture to join Ferrari, who have not produced a drivers' title since 2007, while pitting himself directly against rising star Leclerc.
But Hamilton must ponder how complete his career would be if he joins and wins with Ferrari.
The Briton has openly wondered how it would feel to have the Ferrari faithful roaring him on at Monza and ending the Scuderia's title drought would see his popularity rocket.
He timed his difficult decision to leave McLaren well in 2013 and another opportunity now presents itself.
Hamilton could end his career having seen off a daunting team-mate in Leclerc, surpassed Schumacher's now attainable records of world titles and race wins while winning the championship with a third different team.
If he does that, he would have a compelling case to stand clear of Ayrton Senna and Schumacher to be considered as the greatest driver of all time.
