Mercedes motorsport boss Toto Wolff believes F1 should not have adopted the double-points rule for the Abu Dhabi Grand Prix.
In an attempt to keep the World Championships alive until the final race of the season, Bernie Ecclestone proposed that double points be awarded for the final race of the year.
After much debate, the sport's role players agreed to introduce the rule and it will now come into play in Abu Dhabi, and the season are likely to go down to the wire with Nico Rosberg and Lewis Hamilton neck and neck in the Paddy Power odds for the Drivers' Championship.
Wolff, though, feels they made a mistake.
"I would be very surprised if it didn't come down to Abu Dhabi, to the very famous double points," he told Press Association Sport.
"It means even if you're 30 points behind then you can turn it around in Abu Dhabi if the leading guy retires.
"So maybe Bernie was right, that double points is going to keep the Championship open until the last race. But I don't think it's fair. I don't think we should have done it.
"The reason we did was because the commercial rights holder is head of sponsorship and he cares about the TV audience and the need to keep the excitement until the end, the last race.
"As I said, it looks like he might be right, that the last race is going to be the decisive one, and I would be very surprised if the audiences weren't considerably higher than they would normally be."
With Mercedes duo Rosberg and Hamilton set for an intense battle for title, Paddy Power has Rosberg just ahead, Wolff believes the one that misses out on the title will struggle to shake off the scars.
"Neither of them will care if they won it that way," added Wolff.
"But the one who loses on double points will need some psychological treatment - although we're not there yet."
