The big problem with putting it all on tyres is, how much the tyres over everything else punish the driver for being offline/behind another car.
If you have almost indestructible tyres, the actual ability of the car to handle high speed is a bigger limiter, but thats a GOOD thing this is a team and individual sport, driver vs driver and car vs car, but the title is purely about who gets the best tyre strategy, that is COMPLETELY wrong.
If everyone was really racing, going max out, we'd have more retirements, more blown engines, a more up and down season but mostly MORE DAMN RACING.
Refueling, stint not working you can change strategy, everyone will have to pit again anyway, but you do one bad corner and flat spot your tyres, thats an extra pitstop others won't have to make, it discourages driving fast, discourages overtaking or getting close to the guys infront, its just cack. Maybe its just me but I want to see guys dive up the inside lock up and try and hold position on the exit, I want to see guys pushing the very hardest possible, not lift off and save tyres into corners, and realise that trying to overtake around the outside will just hurt the tyres.
There are many ways to artificially "limit" F1 but tyres is the single worst option as it hurts racing in every way. I'd prefer the cars break due to being pushed to hard, than everyone goes round at a snails pace for fear of hurting a piece of rubber, its mental.
But thats the thing, there used to be situations where one team had an epically fast car, but that insane speed cost them in reliability, or the slow steady car that never broke down(Ferrari last year
) might win the title. The reliability of so many of the cars in the past 2-3 years really shows how within the cars they drive in everything but Q3, and that is just wrong.
Make stupid fast car, do the whole race 8 -10 seconds off that pace..... what? Worlds best cars, worlds best racing, and no one is remotely close to the maximum pace.
THe tyres being so bad also is why there is such a defined racing line, marbles and everyone trying to stay on an identical line make overtaking again more difficult and punish the car/driver, better tyres, less marbles on the track, less penalty for trying to go fast and hard around the outside. It won't necessarily mean we'll get more overtaking, but I want to watch cars racing where the driver has the option rather than knows it will hurt in the long run.
I actually quite want the tyres to be worse, less grip + more life, means driver skill in cornering means more, the ability to control a slide, get a good exit, all part of racing, epic tyres with insane grip but one line and no speed.... not good for racing.
