Religions die hard. It takes an orgy of evidence to change a person's mind on a subject that is integral to their moral and ethical structure.

In the case of Tesla, the mania surrounding it over the past decade has been inextricably bound up with the hysteria of global warming.

For years investors ignored the obvious warning signs that Tesla would never be able to graduate from a boutique, hand-built car manufacturer and technology skunk works to a mass producer.

I've been very hard on Musk in the past, with good reason. But, as a guy with vision I applaud him getting Tesla off the ground and legitimizing the idea of the upscale electric car.

But it was never going to work as a mass production scheme because Musk isn't that guy. He's a dreamer and a schemer, not a builder. And, as I've said multiple times, he should have stepped down as CEO of Tesla ages ago.

A man has got to know his limitations as The Man once said.
