Forgive us for being cynical but we've been following F1 for too long not to be. Mercedes had been literally melting tires from the first race of the season much to the continued embarrassment of higher ups who have seen the Silver Arrows miss their targets since 2010 despite high profile engagements of Michael Schumacher and now Lewis Hamilton.
Solution number one was to blame Pirelli and, after much praise given to the Italian manufacturer for producing a tire which added spice to racing, you saw a very coordinated campaign by the press to discredit the very thing they praised weeks earlier. Would it be evil to point out where those same journalists get their credential and access from?
As for Pirelli, they are facing a PR disaster if forced to leave the sport with the impression they could not make a "good tire", it's no surprise they jumped at the chance to help themselves and a key team, instrumental in renewal of their F1 contract not to mention a big production car tire customer.
You may have noticed the Safety and Medical cars. A fair number of trucks pulling paddock infrastructure have a three pointed star on the front of the cabs.
So is it really a surprise the test happened at all? AMG Petronas got three races worth of running and suddenly their rear suspensions are not eating tires anymore. Mercedes is smiling.
What would be a surprise is if the FIA slap Mercedes with a truly significant penalty. How much tension is there between the Bernie Ecclestone/ FOM and Jean Todt's FIA?
