selecting 1st gear ??

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

F1 cars engage first gear by using electronic control to disengage an obsolete clutch, that is then used to slip dry friction plates and produce and waste heat energy.
This is supposed to connect the drive from the obsolete internal combustion engine to the ancient 19th century layshaft gearbox and then on to the rear wheels.
It works sometimes and other times the engine stalls or the wheels spin out of control.
Bit basic really.
I hear the wheel is pretty old.. seems to be workin pretty well so far.

I'm actually best friends with a certain Technical Director of one of the major F1 teams, which is always on the prowl for visionaries like you who has the guts to call a spade a spade. Do you want me to connect you?

Sure you can but I am already in touch with two teams, so it would have to be under confidentiality.

And the human behind the wheel is a 100,000 year old 'design'. Should really get that crap out of the car.

I think you will find that human development started a lot earlier than 100,000 years ago and is still developing not that it is obvious in some people.
The human vehicle is millions of times more efficient than an F1 car.

Sorry for interrupting this out of thread thread, but I just want to say that a human being has a mechanical efficiency of 20%, given an intake of 2.500 (Kilo) calories per day and a net power of 0.1 Hp.

You could use more efficient vehicles (like a bike) which would increase your efficiency a lot, but then, that's another matter. A crude estimate tells you that a professional biker can produce 300 miles per gallon, give or take.

So, overall, walking on foot, your efficiency is a little better than the efficiency of a car of the '70s, but definitely worse than the efficiency of a modern F1 engine, which (I've heard) is one of the most efficient ICEs to date.

For us to have "millions of times the efficiency" of a car (which would give you around 25.000.000% efficiency) we had to go against thermodynamic laws.

However, hey, if the sun is shining, your girlfriend loves you and you feel fine today compared with an ICE, or, if you confront a cold front, you have fought with your mother in law and you feel that F1 deserves to be in the dustbin of history because modern clutches and gearboxes are a sorry artifact that should be replaced by more modern ways to impulse a car like... (like what?) who am I to interrupt.

Please, move on, without taking seriously this out of thread post in this out of thread thread, hopefully, talking about 1st gear and the misterious art of double clutching.

You are specifying mechanical efficiency Ciros. I am talking about over all efficiency for purpose. Different thing altogether.

Double de clutching is undertaken to allow the driver to brake, declutch, accelerate the engine to bring the input shaft and gear cluster up to the same speed as the output shaft,change to lower gear, then re engage the clutch. It gives a faster and more balanced gear change braking combination.
Heel and toeing is the same process with the addition of using the heel (or toe) at the same time to operate the brake while operating the clutch with the same foot.
Not to be mistaken for left foot braking which is used to increase the pre corner oversteer slide of a pendulum weighted rally car to increase speed and control through a corner apex.
Left foot braking as used on current F1 cars was pioneered through my experiments in the 70.s with two pedal automatic and semi automatic transmission systems and electronic shift controls.

Actually, you operate the brake and throttle with the same foot. You hold the brake with the ball of your right foot and blip the throttle with the side of your foot. That's why pedals are designed so that when the brake pedal is compressed to it's maximum, it is at the same height as the throttle.

Heel and toeing brake and clutch with the left foot, while flooring the throttle with the right?
Guess you invented that method as well Gyro?

More power to the inventors I say!

Usualy correct and I used the side of the foot method in both my cooper S and Escort mexico rally cars. However in my oval circuit mini hot rod I had the pedals staggered to allow for a heel and toe position because the brake pressure needed to be much harder.

But you weren't operating the clutch and brake with the same foot, right? You were operating the brake and throttle with the same foot...

Sorry you are right brake and throttle with the pedals set at the same height with the brake pedal down. I am getting old.
With most racing layshaft dog boxes it is possible to change without using the clutch.
