You also have to consider that the FIA DID sanction this in a way... at least Charlie Whiting and co had approved it, though legal advice was sought, It seems like a storm in a teacup brewed up by Redbull as usual taking over the Ferrari slot as complainers in chief.
End of the day, Pirelli needed 2013 data, from a 2013 car to sort the 2013 tyre problem. No point using a car complying with different regs.
Could it have been handled better? yes. Blacked out helmets? come on guys... wrong? no. Mercedes had problems, they wanted to see how.
losing the young driver test? after that test they had for free, seems only fair, after all, it was Mercedes' QC that suggested it.
All resolved, but Redbull will still whine. They need to paint their cars red and have done with it.
