Why cheap gas can’t kill the electric car

From 2010 to 2014, U.S. electric car sales surged from almost nothing to about 120,000 per year. But the haters and doubters persist. Analysts and investing forums are buzzing about a coming stagnation. After all, in the past seven months the price of oil has collapsed from $115 a barrel to below $50. Gasoline prices have plummeted, too, fast approaching $2 per gallon nationally, and commuters are rejoicing. That means a key selling point for electric vehicles — low fuel costs — is gone.
