What a farce Sunday was. The FIA showing once again how incompetent they are. It's a completely unworkable rule and hey proved it on Sunday.
It is basic physics that air pressure is altered by the temperature. Even I know that the pressure of a tyre drops as the temperature drops. You would have thought someone would have twigged onto this when the tyres weren't at 110 degrees like they are when they are in the tyre warmers with them turned on.
Mercedes set the tyres to the correct pressure as required to when they tyres when in the tyre warmers, they complied with the rules and this was all caused by another rushed rule that has been put in place without a single thought of how to actual enforce it properly.
If you are going to have a minimum starting pressure, you either have to ensure the tyres are all at the same temperature when you measure the pressures, or you have the ability to compensate for the pressure drop that comes with lower temperatures.
But for them to know about it before the race started, and then to only do something about it over an hour into the race is disgraceful, especially if they try and claim it is a safety issue! If it is a safety issue why did they let them start the race?
I did feel a bit sorry for Pirelli up until this because they are getting a lot of abuse for creating tyres as they were asked to, but enforcing this higher pressure simply because Ferrari went to far on them at Spa resulting in the tyre failing because of wear is just taking the p!ss.
Ferrari and Vettel immediately went defensive blaming Pirelli for it when they only have themselves to blame for going with a one-stop strategy that pushed the tyres too far.
Rosberg's tyre failure was unfortunate, tyres can and do fail at times, Vettel's was self-inflicted by Ferrari.
Had Hamilton been stripped of the win I would seriously have just stopped watching altogether.
I will not think twice about it if this stupid tyre pressure rule continues to cause trouble.
