Built around the tyres, yes, but not the rules. Unless you think any team has deliberately designed their cars to go their fastest when driven at 8/10ths?
Keep the rubber, give the teams more sets. No need to change the car designs, but drivers can push in a race rather than driving to set times. 4 stops a race isn't a problem if they are driving flat out.
Surely this is impossible - if a car is being driven at its fastest it would have to be going 10/10's ?
Even if an engine has 17500 rpm, if software etc is limiting it to 15000 , as long as the driver / gear box etc is using 15000 then its at 100% until the software is removed
(Unless Im just being stupid of course lol)
Personally when I read the story about RBR complaining it did come across as "boo hoo, we have now started to lose so we are going to throw toys out of the pram"
I cant see how anything is going to change in regards to better / real racing (at 100% capacity /speed) without a change in aero / mechanical downforce as well as more durable / larger quantities of tyres.
More tyres (and no restrictions on team budgets) isnt going happen with the world economies as they are.
The other thing to consider (and I honestly dont know the answer to this) is that I presume the FIA actually pay Pirelli x amount a year to provide the tyres (and not just through being able to be the sole F1 supplier, and merchandising etc that comes with that). How many more 1000's more tyres would have to be produced /season (given that Inter's /Wets wouldnt change, but Pirelli would have to cover an extra 10 ...15?...20? sets per car of each hard/ medium type of tyre for each race weekend (quick calc says the top 10 places could feasably use 8 sets, ie 5 extra, just in quali)
Therefore imo its a non starter, and the FIA would just go back to the "more durable" option from a few years ago
