First pre-season test
The first day in Jerez is always an interesting one, more so this year as it will be the first time fans will be treated to on-track action.
However, do not look into the times set by drivers too much as they do not mean a thing. After early promise last year, Williams got to the first race in Melbourne and were nowhere near the pace and endured a horrible season for the team.
More proof that the first day - well, the first test as a whole - counts for virtually nothing would be Jenson Button's incredible time at the end of the first day last season. McLaren had no idea that they had assembled the rear suspension of their car incorrectly and somehow gave the car speed - and lots of it.
With Button setting a blistering pace, the field looked scared. Button was overcome with delight on the first day and was quoted by The Guardian: "So it's a good starting point. I'm looking forward to working with it and I'm happy. There are no niggly areas with the car, it's still the starting point and we didn't do any set-up work to improve the balance."
As we know, McLaren went on to endure their worst season in years and failed to make it on to the podium.
The moral of the story here is if your favourite driver is fastest on the first or any day of any test do not stick £10 on them taking the Championship.
