One of the other articles on the L.A. times is reporting that "
U.S. auto sales surge in August to month's highest level in years" so - it's lies, damn lies and statistics time. Electric car sales fell 0.1% as a proportion of total car sales during a period that included the car sales at the "highest level in years."
Consider also that Tesla is still on back-order status and they are gearing up to release two new models of cars. Other than the Tesla, only Nissan has a pure electric generally available on the market - the Leaf - which sold over 120,000 cars last year.
See,
Wikipedia. Ford's focus is also out there, but only in select markets.
Shorter: there's only one mass-market electric car on the market. The Tesla Model S, while definitely a beautiful car, doesn't have the production volume to compete in a market share battle - that's not Tesla's bag - yet. The "stagnation" story is more of the knee-jerk car guy rejection of electrics that has been bouncing around in the media for 30 years now.
