In theory the teams and drivers should have been able to manage this themselves, but Merc and Lewis showed that either they did not have enough information to make the call (accurate measurements from practice sessions, accurate enough predictions for the race etc) to increase the ride heights or wanted to push the boundaries.
As I mentioned before, it needs a much better measure than the pretty meaningless 6g statement (for how long (integration over time is very important), how is it measured, is 6g for 0.2 secs worse than 10g for 0,1 sec, etc) and as I said, there is a lot of research out there already in this area. So it is good to see that the FIA will gather more data and presumably continue to look at the research before issuing the required measures etc for the teams with what the teams needs to do if contravening any new safety rules.
