Following the race at Austin a fortnight ago, there were allegations that some drivers had taken liberties with abusing the track limits at areas of the track that were not heavily policed.
On-board footage of several cars that were being distributed among teams especially showed a number of drivers being well beyond the track edge white lines at Turn 6 of the Circuit of the Americas.
These incidents had largely escaped scrutiny from the FIA as they were not flagged up in the official list of track limits breaches throughout the Austin race.
The images were enough, however, to prompt several teams to query with the FIA at the recent Mexico Grand Prix about why what appeared to be obvious track limit breaches had not been looked at.
It is understood that the FIA’s response was in line with what stewards stated in the aftermath of the USA GP.
It admitted that the CCTV cameras and monitoring infrastructure at that corner were not sufficient to properly police track limits as accurately as is needed, so it could not take matters further.
This had been already highlighted at the Austin race when Williams driver Alex Albon escaped without punishment for multiple breaches of track limits at Turn 6 - beyond the five-second penalty he had been handed for other offences.
