Formula 1 can be a brutal business at times, especially if you are a driver. Job security is not one of the big perks of getting to blast grand prix cars around race tracks every other Sunday. You're either winning or worried, and sometimes even both.
If drivers are not having to look over their shoulders at the next young hotshot ready to push them out, or the threat of the big bucks sponsor willing to pay for their replacement to come in, then they are also having to fight against circumstance that is stopping them showing off their best efforts.
Just as some are lucky enough to get themselves into the right car at the right time, so too on the flipside are those drivers who find themselves in the wrong place at the wrong time. It can be through an unforeseen lack of competitiveness - think of Fernando Alonso in the early McLaren-Honda years. Or it can be through a car that either does not suit their driving style or is simply difficult to drive - think Alex Albon's difficulties with the tricky Red Bull RB16 this season.
