From a purely personal perspective Ian, I'd like zero engineer to driver communication during the race, either audio or via a dash display. Pit boards allowed to advise on safety grounds and race data.
I can understand why you would want that. It would cause confusion and hence less predictability and so would give viewers more things to talk about. So from a viewing perspective, which is clearly very important, could be a good thing to do.
I appreciate fully, that to you as an engineer, it is a fairly repugnant idea and that it will never come to pass. I'd like the engineers to have no influence on the outcome of the race once the flag drops.
Mike, we see it as a team competition and so everyone wants to help the team win in whatever way they can, within the rules. Seems odd to to us say it is a team sport until the flag drops and then it is down to the race driver and the pitstop mechanics.
