In the ‘70s classic movie, “Duel,” a seemingly driverless tanker truck terrorizes an innocent salesperson driving to his next call along a remote stretch of highway. Could a driverless big rig – minus the stalkerish behavior – be part of our future? Daimler Trucks thinks so. In fact, it’s betting big on it and showed its ante with the introduction of its Future Truck 2025 earlier today in Germany. Using the truckmaker’s Highway Pilot system, the prototype semi-truck is capable of driving itself while hauling a full load at speeds exceeding 50 mph, according to the company.
