"I have only one eye. Do you want me to look at the road or the at the speedometer"

Moshe Dayan's quote is an amusing way of revealing the idea that it is impossible to focus on 2 things at the same time. He is recommending that it is impossible to focus on both the roadway and the speedometer at the same time, as he just has one eye. This quote is a suggestion that multitasking is not constantly possible, and that it is necessary to focus on tasks and concentrate on one thing at a time. It also suggests that it is necessary to be familiar with the effects of our actions, and to be mindful of the prospective threats of any scenario. By utilizing humor, Dayan is emphasizing the value of knowing our surroundings and of the prospective consequences of our actions. He is also suggesting that it is important to be mindful of the significance of safety, and to be knowledgeable about the potential risks of any circumstance.
