On Saturday, Formula One driver Jules Bianchi passed away as a result of the injuries he suffered in a crash during last year's Japanese Grand Prix. He is the first Formula One driver to die as a result of a crash in a race for more than two decades. His loss casts a pall over the championship, which continues this weekend at the Hungaroring.
A minute of silence will be held in his honour before the Hungarian Grand Prix begins. Although the racing goes on he will be uppermost in the thoughts of drivers and team members this weekend.
Long odds on 2014 winner
For a sign of just how challenging things are for Mercedes' rivals in Formula One at the moment, consider this: As the field reaches the halfway point of the season at the Hungaroring, the driver who won last year's race at this circuit, Daniel Ricciardo, is on odds of 201.0 to repeat his victory. And only four other non-Mercedes drivers have shorter odds on success.
Both Mercedes drivers have finished on the podium in every race so far this year, and between them they have won eight out of nine races. It's hard to imagine them being beaten at the Hungaroring - but that was the same 12 months ago, and it happened.
Few will fancy backing a Mercedes victory with 1.50 on Hamilton to win and Rosberg on 2.75. However it's surprising to see Rosberg's odds on winning the title have risen as far as 4.50 when he could take the lead in the points standings this weekend.
Williams shone at Silverstone
For 16 laps of the British Grand Prix we had two cars circulating at the front of the field, and neither of them was a Mercedes. Williams stunned the Silverstone crowd by getting both its cars ahead of the two Mercedes in the opening laps. The two drivers finished outside of the top three, but had it not been for a late rain shower a double podium finish was on - and with sharper tactics they might even have been contenders for victory.
Does that make them a worthwhile tip for success in Hungary? Alas probably not.
The Mercedes-powered FW37 is most at home on high-speed circuits like Silverstone. The Hungaroring is slow and twisty and Williams have done as well on tracks like this recently - in Monaco this year neither of their cars qualified inside the top ten. That probably explains why Valtteri Bottas and Felipe Massa have long odds on victory: 41.00 apiece.
A superb turn when the rain appeared allowed Sebastian Vettel to grab third place at Silverstone. But before then Ferrari's dry-weather pace was decidedly disappointing, and the prospect of them challenging Mercedes seems slim.
At 3.00, Kimi Raikkonen's odds on beating his team mate is the longest of any driver. He's on 22.00 to win at the Hungaroring compared to Vettel's 15.00.
A top ten points finish for either of the Sauber drivers - Marcus Ericsson and Felipe Nasr - offers odds of 6.00 at the moment. The pair have both scored points previously this year but have struggled to do so consistently as the team has brought little in the way of upgrades for its car.
Things are looking up for the McLaren drivers now both drivers have got points on the board this year. Fernando Alonso is on 3.00 to take more this weekend, Jenson Button 3.50. But the team who last won this race just three years ago are on 1251 for another victory, showing just how much work they have to do.
