The most unwelcome news from the German Grand Prix wasn't anything to do with tyres or pitlane safety or even the fact that Felipe Massa keeps locking his brakes and spinning his Ferrari F138.
It was the news that Sauber were unable to keep up the payments to their star driver, Nico Hulkenberg.
Last year Sauber finished 6th in the Constructor's table and scored 126 points. (This is where McLaren will finish if they don't pull their finger out) You have to start worrying when the 6th best team in F1 is struggling for money.
This week we have had the announcements that Honda are setting up a factory in Milton Keynes and that they are going to fire up their new 2015 turbo engine this autumn. Honda's return was great news for F1 because it signalled the apparent health of the sport and its ability to attract manufacturers back in.
It should be remembered that BMW left the sport with great haste, while Honda were perfect gents and left Ross Brawn a great legacy to continue - so great that he won the 2009 World Championships.
But Honda's return, though good for those who like to sit misty-eyed with their collection of VHS highlights of Prost and Senna battling it out in their McLaren-Hondas, is actually part of a change that is ramping up costs. Next year engines will cost teams double what they cost this year. The new turbo engines, though attractive to those who want to spin off new energy recovery technology come with a much higher price tag. Plus cars are never more expensive when there is a big change of technical rules - which is what we get in 2014
So if Sauber cannot afford their wage bill with the old, lower-cost V8s, and they are heading for a season where they are battling Williams for 8th and 9th place and will get less money at the end of the year than 2012, what hope is there for them for 2014 ? Loaning your wind tunnel out isn't going to pay all the bills.
Williams are in a similar position but at least have developed more parallel businesses, the way McLaren have spawned a series of technology companies that sit alongside the racing team. This week it was announced that Williams had been awarded government funding to develop flywheel-based energy storage systems originally destined for use in Formula 1 ( a different kind of KERS that ultimately wasn't adopted in the sport).
The grant is from the Energy Entrepreneurs Fund and is aimed at encouraging low-carbon innovations. The original Williams KERS system has been adapted for use in hybrid buses, while it is developing flywheel systems for metro systems, trams and even monorails.
Neither Sauber, sitting with seven points, and Williams, currently on zero points, can hope to earn megabucks from their placing in the constructor's tables this year, but still have to compete with Red Bull who have an undisclosed budget. Now that Mercedes are emerging as a serious title contender to their crowns, this won't result in any less spending from the high-caffeine fizzy fruit drink team.
The deeply-pocketed Mercedes team, who have five former technical directors on their books, could become the dominant force in the next five years. This is why the FIA need to start taking the Resource Restriction Agreement (RRA) seriously and imposing it on teams - starting with Red Bull who have always fought it.
The teams need to act in a concerted fashion to prise more money out of Bernie Ecclestone and the sport's commercial rights holder, CVC. If we are to avoid the sudden collapse of teams and the polarization into the haves and have-nots in F1, something needs to be done. The likelihood that it will be done is very slim. The fact that a good mid-grid team like Sauber cannot afford to pay one of their drivers is surely evidence enough that we are standing on the precipice again.
