Broberg claims that road trains are a step towards autonomous vehicles, telling Autocar that:Road trains allow a driver to use their time better, drive safer, reduce congestion and improve the environment. You're always following another car, so why not let the driving be done by someone else?
Broberg admits that there are legal and social issues associated with road trains, but says that:I believe they will happen. From a technological point of view, it's challenging, but possible.
We know there are environmental benefits as well, so let's hope this idea actually leaves the station some day.Until you try it, you cannot grasp these issues.
