The radio rules were brought in because drivers like nico especially were basically being coached how to drive. That should be banned but information on settings etc should be fine as there not the job of the driver to know, how to drive the track is what they should know themselves
I disagree very much with this statement. I think it is a driver's job to know how his engine functions, what settings it has, what each setting does and what setting he needs to be in for whatever tactic he and his team of engineers have decided on.
If the driver is really exceptional, he will also be able to call an audible and switch to appropriate settings on his own. Much like how guys like Schumacher would constantly change his differential during a lap based on the upcoming corner or sections of the track, I feel this makes the difference between drivers that are good at turning a wheel and drivers that are exceptionally good at analysing how their car works and can work to his benefit.
F1 in particular is a team sport, supposedly the pinnacle of engineering, it shouldn't be too much to ask of the top drivers of the world to understand and feel their car on a deeper level than "know how to turn into a corner without breaking out". That is what makes the difference between a driver and a really good driver. If there's too many settings for them to take care off or things are too complicated, they need to get some UID experts to work with their software engineers to simplify it for said driver.
In this case, it is fine that they told him he had a problem with his gearbox, I'm even okay with them saying he can fix it with a soft reset, but I disagree that they need to give the driver specific engine modes to set, or specific instructions on what to avoid doing. If that means his gearbox goes broke, well good.
