Didn't Jonathan Neale say a week ago they could probably fix the PU without even using one more Token? So yes, they can change a lot on reliability basis.
Anyways, of to a hopefully better FP2.
Edit: Sooooo....
Either it was a great FP2 becaus they are so confident in the Car that they don't even run Race Simulations or it was bad because we actualy seem to go backwards on reliability.....
