Move Aside Google Car, The Self-Driving Truck Is In Your Rear-View Mirror

In the U.S., heavy trucks represent roughly 5% of the total vehicle population, but consume 20% of total transportation fuel. This may seem like these trucks are not as fuel efficient as cars, but these trucks haul loads that are, on average, 22 times the load of a car, with engines that are six times as large as a typical car engine. This clearly proves how trucks, not just in the U.S., but also in all parts of the world, have the most fuel-efficient powertrain technologies.
