Well strictly speaking you never actually asked a question, but ok then i will comment on what you said.
I see you are located in Switzerland, but i dont know if thats where you learned to drive.
I learned to drive in the UK in 1984, and my instructor told me there was no need to go down every gear in sequence when coming to a full stop.
For example when approaching a red traffic light i was taught to change down into third then come off the gas and let engine braking slow the car, brake when necessary then press down on the clutch when the car is travelling around 10mph.
I was also taught that it is acceptable to split the box when downchanging after braking to match gearbox to road speed, eg.change directly from 4th to 2nd.
I used these methods on my test and passed first time. However i do know that some other instructors at that time were still teaching the use every gear in sequence method for downchanging.
I believe modern methods of teaching are similar to how i was taught, ie. it is not necessary to use every gear in sequence when downchanging.
When driving on public roads there is simply no need to drive like this because it most certainly will cause extra wear and tear, although relatively speaking it will probably be very little.
I like to drive very briskly when the mood takes me but i also have mechanical sympathy for my car, so my normal driving style is not to downchange in sequence with the engine revs rising and falling....rising and falling...rising and falling.
But hey.....everybody has their own driving style, and i am certainly not attempting to tell anybody how to drive.
Im sure my girlfriend will disagree with that last statement. :lol:
