FIA race director Charlie Whiting has admitted that the governing body is looking again at the rule that would see lapped cars drop to the rear of the field when the safety car is deployed in F1.
In the past, lapped cars amongst the leaders were waved through to allow the front-runners to take the restart in order although the rule was dropped ahead of the 2010 season.
It means that in the event of a caution period, lapped cars now take the restart mixed up with the rest of the field – a system which has proved to be unpopular with drivers fighting for position who find themselves trapped behind a lapped car when the race resumes.
Speaking ahead of the European Grand Prix on a range of issues, Whiting was quizzed about safety car regulations following recent incidents in Monaco and Canada, and he revealed that a rule where lapped cars would be put to the back of the field was being considered.
“It's on the agenda,” Whiting revealed. “We've attempted this before, as you know, but the procedure then was a bit complicated. I think there are simpler ways of doing it and we've discussed a few, but we haven't been able to agree on anything.
“I agree that when the restart comes you don't want lapped cars there as it dilutes the field.”
Whiting also defended the decision to suspend the Canadian race due to adverse weather conditions although he admitted that there were things to consider on the back of the Montreal event – which eventually came to a finish some four hours after the lights had gone out for the start.
“The decisions that needed to be taken weren't particularly hard,” he said. “When it rained it was quite clear we needed to stop the race.
“I think there are two things we've learned from suspending a race this year. One is we need to discuss with the teams whether or not working on cars should be allowed and whether a change of tyres should be allowed during a [race] suspension.
“Also - and I never would have thought it - we maybe need to think about a maximum time for the race. At the moment, as you know, the time for any suspension is added onto the two hours [maximum race time], that's why we ran for four hours and four minutes. We're going to discuss that with the teams.
“I think the procedures worked perfectly well. Unfortunately, quite a few spectators left. I don't know what happened with television broadcasts, that must have been quite difficult for TV companies, to know when to cut to something else and how long it was going to be. It would be nice to have been able to say during the suspension how long it might be, but it was almost impossible to say, because apart from knowing when the rain was likely to stop there was the problem of clearing up water on the track, which was quite serious. I think the guys that did hang around got a good show.”
