Tesla needs to get production capacity on track fast, or they will get left in the dust as other major players hop on board the EV wagon.
When I initially read your comment I was inclined to disagree with another automaker incumbent-smashing opinion but upon researching, I have to say, 2,000 units a month in the nascent mainstream market for EV's is definitely impressive. Kudos to GM there
Maybe some of the major car manufacturers will build their own battery plants or some new supplier will fill the market demand, but that takes time. Until then, the incumbent manufacturers will continue to sell mostly gas cars because they have no alternative.
