Connected cars are going to become increasingly common on our roads. IHS Automotive estimates that by 2020, the market will grow sixfold to 152 million vehicles. Gartner is even more optimistic, predicting that a quarter of a billion cars on our roads will be connected by 2020. The market for smart vehicles is certainly set for takeoff and many analysts predict they could revolutionize the world of automobiles in much the same way smartphoneshave changed the face of telecommunications.
