My knowledge in ergonomics is slim, but I do know that we prefer fingers over palms. The fact mentioned in Turnfast.com, which suggests gripping the wheel from the palm is wrong. Therefore, it would seem that pulling is indeed more sensitive. With modern cars we are talking about light racks and power steering, I doubt how much power from stronger muscles we actually need. As racers, we do our best to grip the wheel is lightly as possible to recieve the most feedback, and whenever a pushing or shuffling motion is applied and the upper body is brought into use, I feel it causing me to apply a greater effort.

Thank you. Can you rule pulling more sensitive than pushing in spite of wrist movement during a pulling movement? Can you citate a source? This is simply a long debate and I want proof in order to end it.

The information citated from Turnfast.com is percisely the reason why I am asking: They state that Pushing is better because the wrist stays firmly positioned. I was always taught to use the other hand because the muscles generating the movement are more sensitive in nature. Can any of you confirm or deny any of these claims, from an Ergonomic source, and not a racing-related source.

The problem with about everything in your post is that it does not consider the development in the world of motor cars. Modern cars, even road cars, have enough seat adjustment options available to reach a very suitable position. With the shoulders on a certain height, must the palms be placed in a parallel height or preferably slightly lower? About steering, the 10 to-2 position is the grip of the wheel which relates more closely to the former subject of seating position. Additionally, it was a custom of older cars where the rim was very large and holding it across it's diameter would have the driver place his hands extremly apart. Modern rims are much better controlled when the hands are in 9 and 3. About shuffling the wheel, I know for a fact that modern rims are also light enough to be rotated more smoothly in one hand movement rather than a succession of hand movements. My question is which hand gives you better control and less effort?

Hi, I am a competetor and instructor of motorsport. I try to live up to the name motor-sport and teach my drivers not to underestimate the physical skill nessecary in terms of correct body positioning, utilization of vision, etcetra. As an instructor, I have two issues in need of solving: 1. Regarding our seating position: Some instructors teach their students to seat with the shoulders on the seat and the palms on the wheel in parallel heights. Others, such as me, teach a position where the palms are slightly lower than the shoulders, approximatly 5cm. I have heared it has to do with blood circulation, but without detail or proof. What to do and how? 2. Regarding the manner in which we steer our cars: Some prefer to use the hand in the direction of the turn in a pulling movement, some push with the opposite hand. As an advocate of the pulling method, I was taught the pulling movement involves a wider range of muscles including some very gentle muscles of finer motor skill, like forearm, palm and finger muscles, and that pushing encorprates stern upper body stregth resulting in less sensitivity and more physical effort. The claim of the "Pushers", however, is that during pulling the wrist becomes quite bent, allowing for less smooth contorl. I have not been able to prove or disqualify this excuse, but it appears that the feeling in the fingers and palms remain identical when the wrist is twisted downwards (fingers aimed down). So, which hand movement is prefered?
