Mercedes F1 team boss Niki Lauda has slammed Formula One for being 'over regulated', and says Finn Kimi Raikkonen was partly to blame for his own big first lap accident in Sunday's British Grand Prix.
The three-time world champion Austrian said he could not understand Raikkonen's driving in the accident, which delayed the race for an hour.

And he suggested that the delay, to repair a piece of crash barrier, was too long and unnecessary - and may have cost the sport large numbers of television viewers on a day when it was competing with the Tour de France and the Wimbledon men's tennis single final.
"This over nursing of F1, being over cautious, over controlling and over regulating drives me mad. And this little guardrail issue is another example," he said.
