" Altogether, the world of autos—and their fuel suppliers—has become the arena for a new kind of competition. It is no longer just about selling cars to consumers for personal use. No longer just automakers versus automakers, no longer gasoline brands versus gasoline brands. It has become multidimensional. Gasoline-powered cars versus electric cars. Personal ownership of cars versus mobility services. And people-operated cars versus robotic driverless cars. The result is a battle among technologies and business models, and a struggle for market share. Change does happen, just not overnight "
