Telling Rosberg what was wrong was OK, advising him how to get round it was "advice" on how to drive the car, which is a no-no. I agree that drivers should not be coached on how to go faster, but think it unreasonable for a driver to know what it takes 10 on the pit wall and a multiple back in the factory to figure out...
This closely equates to my own position on the matter, however the whole point is that no driver, on any team, is capable of knowing what a team of analysis engineers on-the-spot are required to figure out. Its a pretty level field in that respect. If the driver makes a call that is wrong,and gets stuck in a gear or explodes the entire box or cooks an engine - that's the unknown quantity that should always remain a part of racing.
I love data collection and analysis - I'm always amazed at what you can derive from it. However being able to accurately predict everything all the time removes too much of the sport. There should be drama and agony, heroic wins and heartbreaking losses (people aside, obviously). We are slowing eroding the elements that make it engaging.
We want disparities born of intelligence and cleverness, not money (no, I have absolutely no idea how you do that), strong underdogs with a real chance once in a while, a villain and a hero, drama, danger (relative) and all the rest of the elements required to make an experience that pulls you in.
I'm not suggesting we want F1 to become WWE wrestling or afternoon soap operas, but the answer to the declining viewership is undoubtedly tied to ever more antiseptic events.
The rule needs to be stricter, not because its not fair, not because we need simpler technology, but because we need more drama.
Or not. Whatever.
