There is much talk of successes against terrorism, in part as the justification for placing restrictions on long- and hard-won freedoms from oppressive government. But as the bombs placed at the route for the Boston Marathon shows, identifying and containing terrorist threats is next to impossible.
It's not the fault of the track and it's not the fault of the Formula One teams. For sure, it's not the fault of the drivers. The 2013 Chinese Grand Prix in Shanghai proved for once and for all that the tyres dictate the strategy and - even more ridiculously - the racing. If you thought team orders affect who races who, you need to hear the pit-to-car radios in the Shanghai race. And dust off that Scalextric that's been hibernating in the attic.
The Qatar MotoGP race launched the 2013 season, the entry to the senior class of double champion Marc Marquez, a new qualifying format - and proof that Valentino Rossi plans on winning a record 10th World Championship.
The official word from Red Bull Racing is that Sebastian Vettel and Mark Webber have "settled" the issue that arose when Vettel ignored team orders in Malaysia and took away Webber's victory. But as always, the devil is in the detail.
The most fun of the weekend in Malaysia was not the (rather sad) race weekend concert but when Lewis Hamilton forgot that he's changed teams and is now driving for Mercedes. The McLaren pit crew who watched him pull in between the lines - with tyres ready - waited patiently while he worked out his error and set off for his own box further down the pit lane. No one else had anything to smile about, including eventual winner, Vettel. He broke team orders to stay behind Webber but says "you know I’m not sorry to win."
Melbourne: the autumn leaves, the winter rain, the summer sun and a spring in the step of all in Formula One as they arrive for the start of the new season. Then it all went rather weird and it's difficult to feel ultra-pleased with Kimi Raikkonen's win in his Lotus branded Renault which is a shame because a win's a win, isn't it?
Given Ferrari's history of stress-testing and even breaking the rules, often with the support of stewards and the FIA, it's a bit rich that they asked the FIA to review the stewards' decision over a pass by Sebastian Vettel on Verne in the Brazilian Grand Prix.
How do they do that? It's usual for motor racing circuits to have a micro-climate and no one has ever been able to understand why it is so. But when MotoGP reported from Sepang that "the track was dry by 11:30" yesterday, Kuala Lumpur city centre, just 40 km away was settling in for heavy rain that brought city traffic to a standstill.
In one of the least surprising announcements as to 2013 drivers, the Williams F1 team has confirmed Pastor Maldonado and Valtteri Bottas will pilot its cars next year. So Bruno Senna is looking for a new seat.
Fans were exhausted, commentators were breathless, drivers were either elated to seemingly dangerous degree or as flat as a flat thing. And all because the Brazilian Grand Prix, the last race of the 2012 Formula One season, was impossibly exciting. If anyone ever mentions a traffic-light grand-prix, tell them to watch this for the moments the lights went out, the world went crazy. And it didn't stop until the leaders had already finished
Before the US Grand Prix at Circuit of the Americas in Austin, Texas, there was much criticism of the track: overtaking would be difficult, the tyres chosen by Pirelli were wrong, the tight corners into long straights would lead to bunching and then a train down the straight, and so on. They were wrong.
Speaking at the first press conference for the first US Grand Prix yesterday, Sebastian Vettel told the global F1 audience to not to watch F1 if they are "sensitive." Bryan Edwards, our motor sport editor, writes him an open letter.
The future of the recent development of podium interviews must be in doubt as two Formula One champions disgrace themselves and the sport by the use of coarse - in one case foul - language live across the conservative Abu Dhabi landscape and the world's TV screens.
