Whether you call them trucks, big rigs, semis, 18-wheelers, or the actually correct "tractor-trailers," these behemoths of the road are among the most under-appreciated vehicles in existence.
Unless you're entirely self-sufficient (and if you're reading this, you're not), you depend on tractor-trailers for a whole lot more than you probably realize -- which is why advances in trucking technology will impact you far more than any fancy high-tech developments coming to your car. Best part is, you don't have to do a single thing to reap the benefits, ranging from safer roads to more money in your pocket.
A handful of players are in the race to roll out electric and autonomous trucks -- Elon Musk, for example, recently announced Tesla’s plans to develop electric tractor-trailers that can drive themselves. Typical of Musk, his timeline was a bit vague, but let’s take a look at some of the cool-as-hell truck concepts that are already hitting highways.
