All we can do as fans is keep banging on about it until a decision is made to enforce the regulations. However, I would highly recommend anyone who is tempted to think it would be an easy or simple matter to enforce this to go on Youtube and look for the 2012 V8 Supercar races at Surfers Paradise, to see how big a hole the stewards can dig themselves if they give out warnings and penalties haphazardly and inconsistently.
Let's say there are six corners where people are running wide off the track (at Budhh it's probably more than that), over a qualifying session everybody will do between two and four hot laps, that's up to 576 instances for Q1, 384 instances for Q2 and 240 instances for Q3 of a car passing through a relevant corner on a hot lap, and there needs to be a judge of fact positioned at the corner, or in race control watching a fixed enforcement camara at said corner, making sure every violation is spotted. It's no good if you only enforce the rules when the FOM cameras happen to be watching or when the Race Director happens to notice.
Similarly in the race, if everybody finishes and nobody is lapped, there would be 8640 instances of cars passing through the relevant corners, and in each case it has to be decided not only whether the car left the track, but also whether the car left the track without justifiable reason. If it left the track with justifiable reason, it has to be decided whether an advantage was gained. It's borderline unenforceable at the moment. At minimum, a veritable army of official judges of fact are needed, to report off-track incidents as they happen and to ensure the FIA knows exactly how many times a particular car has gone off track. It's not something the stewards can be expected to sort out without systematic monitoring to ensure equal treatment of all competitors.
