People talk a lot about driverless trucks, which I think are unfeasible with current and foreseeable technology. Yet I haven’t seen anyone talk about trains of trucks. This could be an interesting way to use driver assistance technologies to reduce the number of drivers per truck. You’d put a driver on the front truck only, and the rest would be following closely by themselves.
It’s definitely not without problems. For example, what do you do when a red light causes a long train of trucks to split?
Does anyone know if this idea has been explored?
