Pulling away in manual car. Only using clutch no gas

So i've just started taking my driving lessons, doing the beginners course which is 4 lessons as i've had aboslutely no driving experience in the past
yesterday was my second lesson and I drove all the way home which i was quite proud of - obviously with him telling me what to do
The only thing is, when i'm pulling away from being parked up i'm being taught to fully release the clutch… The car starts moving slowly, my foot is completely off the clutch and then i start slowly accelerating

But, today i went into my mams car, after arguing for about half an hour that my foot is fully off the clutch before accelerating, so she let me go in her car to show her what i was doing… And she was right, the car just jumps and its impossible to do

so how comes in my instructors car i slowly release the clutch, fully, then accelerate?
getting myself stressed, surely pulling away properly should be the first thing i'm taugh? But then again i'm having no problems pulling away the way i have been in his car

PS… Its a ford fiesta, only about 2 year old

Your instructors car is a diesel engined one - they mostly use them now as they are harder to stall.

They are harder to stall as a deisel engine makes a lot more pulling power at slow engine speeds than a petrol engine. With all but very light petrol cars and very large engined petrol cars you always need to add accelerator pressure at the same time as coming off the clutch

It might just be the car itself. I drove a jeep that would allow you to take your foot completely off the clutch slowly without stalling and no gas. Maybe your moms car has an assisted start or something that causes it to stall if the gas isn't pushed. But either way you won't hurt the car

Depends on a number if things.
Is the car Diesel or petrol?
Much easier in a diesel car.
Does it have an anti staff system? Many modern cars do so it effectively gives the engine gas to stop it stalling.
This is all dependent on the car you are driving. I can do that trick in most cars by careful use of the clutch.(I have had to on one occasion when the throttle linkage broke at traffic lights. I could move the car to the side and then fix it.)

Different clutches are different, you mothers car will too, you will just have to learn how.

In my experience you can take off in most any manual transmission car without hitting the accelerator if you work the clutch right. Also in my experience this isn't usually something you can do in typical driving in traffic situations as it takes more time to get the vehicle rolling. This is how I taught my kids to drive as it forces the driver to "feel" out the clutch to see exactly where everything engages. All vehicles will be different though, release the clutch slowly and feel it out; if the vehicle bogs down and starts to "stutter" you are releasing the clutch too quickly.

Find another instructor, one who will teach you how to drive properly, this guy's teaching you wrong.

I thought all cars would stall doing that but apparently not. The car you are learning on is unusual as your Mam probably told you. If I were you I would learn to drive an automatic first and take up stick driving later. Driving is hard enough to learn without shifting being added to it.

Hi each car is different and they all drive differently. So there's nothing wrong just your in expirence yes as time passes we do learn to adapt to different cars. Having own same cars and same models they too can be different.
so there's nothing wrong with your instructor or his methods. As you will be learning to drive and take our test in his car there will be no problem.
As for all the nonsense answers i have seen above this is what you have to be aware of in life. So many talk rubbish.
so after 4 hours driving your driving knowledge is currently zero. Time and practice will improve your knowledge so in about 20 years time, you would look back at this as being nothing to worry about.
Happy Motoring.
