Road trains have been proposed for decades as a safe eco-solution for driving cars on freeways, and finally a two-car test is hitting the streets in Europe this month. Semi-autonomous driving could make your commute to work a pleasure instead of pain.
The concept of road trains--up to eight vehicles zooming down the road
together--has long been considered a faster, safer, and greener way of
traveling long distances by car. And now, thanks to a European
Union-financed project, the idea could be coming to a freeway near you
(that is, if you live on the other side of the Atlantic Ocean).
