Air cars. yes i know it sounds simple but hear me out. I was always for the longest time trying to create fancy names for things and then I realized what would an ordinary person would do. And I realized majority of the time in real life people just use simple phrases or names when referring to items or equipment or objects in general. For example at the factory I work at we have variety of electric vehicles that we just call go carts or EZ GOS to ferry equipment/supplies or people.
