I agree with the people/things nominated, however I would swap Vandoorne and Vettel around. While losing every qualification head-to-head against your team-mate who also brought in something like 75% of the team's points for the season is by all accounts a pathetically bad season, I feel this is less rejectful than:
- Having the lead in the championship for half the season
- Having the fastest car in the championship for most of the season
- Having a team that enforces the team order from day 1 of the season
- Having a support driver that is actually capable of racing the other title contenders and doing the job expected of a support driver (sorry Bottas, but you don't have that killer instinct that Kimi has)
And still managing to lose the championship with a couple of races to go due to a series of unforced errors (for example driving too fast in the wet and binning the car, hitting other cars in woefully over-enthusiastic overtakes that had at most a 10% chance of working and throwing away pole position due to Q3 errors - this was not only his fault, the team should have backed him up better in particular in Monza).
2018 was THE opportunity for Ferrari to break Mercedes' and Hamilton's run of championships. Vettel had all the advantages he could have hoped for, and still bottled it. That's why I would put him in third and not fifth.
In 2019 Vettel will have a much less compliant driver in the other seat, who is out to prove why Ferrari gave him one of the most prestigious jobs in motor racing. If Vettel continues 2019 where he left off in 2018, he will find himself becoming the highest paid support driver on the grid.
