Final answer:
In driving, the push-pull steering method is generally recommended for safety and control. It involves pushing the steering wheel up with one hand and pulling it down with the other without crossing hands, as opposed to the hand-over-hand technique.
Step-by-step explanation:
What is the recommended steering technique: Hand-over-hand or push-pull?
In the context of operating a motor vehicle, recommended steering methods include hand-over-hand and push-pull. The hand-over-hand technique involves one hand pulling the steering wheel down while the other hand crosses over to pull the wheel further down. This method is often used for sharp turns. On the other hand, the push-pull technique, also known as the shuffle steering, involves pushing the steering wheel up with one hand and pulling it down with the other, without crossing hands. This method is recommended for general driving because it allows the driver to keep better control and steadiness, and reduces the risk of injuries during airbag deployment in an accident.
The question seems to mix two separate concepts: a physics problem regarding the force required to slide a block of ice when pushing or pulling, and a practical driving technique. In terms of physics, the answer is that pulling a block of ice typically requires less force than pushing, due to the angles of force application and friction considerations. But in a practical sense for driving, the push-pull steering method is generally considered safer and more efficient.
