The ability to quickly and accurately shift our gaze and orient our head allows us to gather information from our environment, track moving objects, and engage in social interactions. These movements are also tightly linked to our cognitive processes, such as attention, memory, and decision-making. Additionally, the intricate coordination of eye and head movements showcases the complexity and precision of the human nervous system, making them a fascinating area of study for researchers in fields such as neuroscience and psychology. **

Electrifying truck traffic would also require significant investment in infrastructure and technology, such as building charging stations and developing electric truck models. Overall, while underground power lines next to highways could potentially electrify truck traffic, the practical and financial challenges make it a less feasible option at this time. **
