As usual you're writing nonsense without checking out what was actually happening. You've probably watched highlights on youtube or listened to croft on sky and then went to write this comment.
Yes, understeery car is slow in nature. If you can't have perfect balance then in most cases you want just a little bit of oversteer (kinda like ferrari has currently).
Understeer is the worst kind of unabalance, slow and grains rubber easily with the front constantly scrubbing off on tarmac.
Perez' tyre management skills are just a myth at this point. Even from his sauber days it was mostly down to the car being good on tyres, same as lotus. He's had no advantages to speak of against verstappen since he joined red bull. Even in melbourne he put in a few fast laps after he overtook hamilton, then he dropped off and ended up further behind verstappen who was struggling with graining. So either Perez is so slow Verstappen can beat him with heavy graining, or he had problems of his own with graining.
After they switched to hard verstappen was just on a different level vs perez, 2.6s faster on out lap (!). Perez was so bad at warming up hard compound he managed to get jumped by hamilton, something that would never happen to Verstappen. These things add up.
And I am talking nonsense. What's a worse kind of imbalance and do you have an explanation for this?
Oversteer is more unstable than understeer. It's better to have an understeering car that is fast, than an oversteering one that is not as fast over the whole race. An oversteering imbalance is not self correcting like an understeering imbalance.
Driver's who like oversteer don't actually setup the car to have oversteer. They just want the car to feel more neutral; which is easier to rotate. Some driver's do not feel comfortable with too much of a neutral car, because of how they get feedback from it. Kimi was famous for wanting a certain feeling on the front axle, and he needed special power steering to give him this.
An oversteering car is not inherently superior. So maybe you should be sure about what you understand first.
The best setup is the one that finishes the race the fastest and gets the driver to perform his best.
In this formula, the tyre wear is very important. If a driver likes to oversteer he is going to feel good for a few laps then realize he has overheated his rear tyres, or scrubbed off too much on the fronts, or whatever it is he does to correct an increasing imbalance like an oversteer. It works the tyres more.
Understeer is the worst, because you cant correct it. The only way to correct it is to let your foot of throttle and hope for the best. Oversteer on the other hand is managable trough steering corrections and adjusting your throttle. Also when you have understeer and the front tyres grip it leads to suddenly oversteer.
Now we can all agree, some drivers prefer oversteer and some like understeer. But seeing the footage, this car looks looks like a full loaded container ship (see turn 15 australian GP)
He said imbalance. What makes it worse is that it's an aero dependent car. An oversteering aero car is detrimental over a race. Once it has that imbalance, the imbalance will increase on its own and the car will want to swap ends.
An understeering car will not increase imbalance on its own, you will have to press the throttle more, or the tyres will have to lose grip completely. But in an aero car with wings and end plates, the car will correct itself even more with an understeer, remember those shark fins we used to see on the older cars. An oversteering car will have no self correction; the driver will have to do this by hacking at the wheel which is inefficient.
It is just a fact that an oversteering car takes more out of the tyres because it's more unstable.
