The cacophony of criticism against the current state of Formula 1 has grown steadily and relentlessly, underlined by increasing unpopularity - with its shrinking fanbase, as well as its own participants.
F1's top drivers - those who should be its greatest champions - bemoan its flaws. Lewis Hamilton is exasperated by tyres that turn to mush if he drives too fast; Sebastian Vettel talks of F1 being overly complicated by technology only a minority of boffins understand.
Jenson Button says Formula 1 has "a long way to go before it's good again", while his McLaren-Honda team-mate Fernando Alonso suggests F1's off-track political circus has become more engaging than the on-track contest that is meant to be its centrepiece.
