Had a project manager on a patrol boat project I was working on who was adamant that no mic or control head would be placed in the overhad of the pilot house, citing a navy study that suggested that swinging mic cords would hyptonize and put crew members to sleep while on watch. Of course the first thing the captains did was have the radio control heads re-located to the overhead where it was practical from an operators standpoint to have them to efficiently operate the vessel. Of course their experience also told them easilly that if you have crew falling asleep on watch, you have a crew rest issue, and not a swinging mic cord issue
Point being, if you are tired enough to leave your lane while driving, cruise control or no, you are probably going to leave your lane and shouldn’t be driving at that time. IE: it is not a machine issue it is an operator issue…
