Formula One's race stewards are considering a system which would allow them to review previous races to improve the consistency of decisions.
The 2016 season saw the consistency of penalties called into question by many of the drivers on the grid, with punishments seeming to vary from race to race. At an FIA meeting in Vienna this week the stewards agreed that is a key issue to address going into next season.
"We went through a lot of rules and looked at how we can work with the FIA to tidy up the wording, enabling us to take quicker decisions," stewards' chairman Garry Connelly said. "We talked a lot about how we can achieve better consistency.
"We think that more meetings and more reviews of past decisions are necessary, so that we all understand how each panel of stewards is treating a particular situation, especially where it's necessary for the stewards to make a subjective ruling, on a dangerous driving charge for example. That is quite a subjective issue.
"These are obviously decisions that are made collectively but understanding how those decisions can be made more consistent is valuable."
One way of achieving this appears to be regular video conferences to evaluate decisions made at previous races, a system used by Germany's governing body, Deutscher Motor Sport Bund, to ensure greater consistency in future decisions.
"The stewards get together by video link to look back at incidents and discuss the decisions made. We thought that might be good thing to do every three or four races."
The Mexican Grand Prix was one of the more controversial of the season, with Lewis Hamilton escaping a penalty for going across the first chicane at the start, only for Max Verstappen to get a time penalty for doing the same towards the end of the race. In that instance, Hamilton was judged not to have gained a lasting advantage.
Connelly suggests one way around this sort of confusion in future is to ensure circuits modify corners in a way which punishes drivers for making mistakes, taking the decision out of the stewards' hands.
"The point we also made is that the rules say a driver can rejoin the track as long as you do it safely and gain no lasting advantage.The word lasting is again very subjective. Does it mean lasting for 500m, until the next turn, the next few laps or the whole race?
"That subjectivity is removed if the circuit is modified or designed to immediately disadvantage a driver if he does go off track."
