The novelty of a vast number of different race winners will wear off and Formula One must avoid being too random to keep fans glued to the action, says Mercedes team boss Ross Brawn.
“For F1, we must make sure that the random factor is not too strong,” he said on Wednesday.
Seven different drivers won the first seven races of this year's championship, the first time that had occurred, and Brawn hopes the second half of the season will be less unpredictable.
“I think there have been some elements of this year that have been exciting, but the excitement) will fade after a while if it stays too random,” Brawn said.
“What we cannot have in motorsport is a randomness where you don't know who is going to win, and that you could work really hard to improve the car but your car doesn't suit the conditions and you are not competitive. That is not where we want to be.”
Where Britain's Lewis Hamilton wants to be has reportedly been made clearer after he told his McLaren boss that he is keen to sign a new contract.
Hamilton in the last year of his deal but speculation has been widespread linking him with a shift to another Formula One team, possibly Red Bull.
But McLaren's Martin Whitmarsh has indicated Hamilton will not be leaving anytime soon.
“If Lewis wants to stay in the team, which he has told me he does, then he should do. And if we want to keep him, then we should do,” Whitmarsh said.
“Lewis and I have spoken two or three times at length; our conversations have been about how we are going to beat the other teams, and how we are going to try and win races.”
The Formula One championship will resume at Spa Francorchamps in Belgium on August 31.
