When some of the iconic car manufacturers announce that they are going to overhaul their fleet, you must take notice. Over the past few months, American and European giants such as General Motors, Ford, Audi and Volkswagen have announced plans to phase out manufacturing of diesel and petrol-powered cars, and send out only electric vehicles over the next decade and a half. Granted, Ford and Volkswagen will cover only the European market initially. At the other end of the world, Japanese automaker Honda has set itself a deadline of 2040.
