Electric cars are developing quickly technologically, culturally, and economically. Costs of production are down. Prices are down. Acceptance is up. Those trends, and the feedback between them, mean electric cars are now cheaper to own and operate that gasoline powered cars.
“At current rates, sales of electric cars could outstrip diesel cars as early as May 2019” – The Guardian
Part of the benefit is subsidies, though the trend is so strong that the subsidies may not matter within the next few years. Hybrids, however, are more expensive than either all-electric or all-gas because each car contains both systems, raising part count, complexity, and failure rates. This is a dramatic change for an industry that considered any non-gas vehicle to be a curiosity only a few years ago. The disruption within the industry will also affect oil demand, electricity demand, as well as both infrastructures.
