Tesla is really nothing special. It has one massive advantage: the supercharger network. Other than that, it has an excellent powertrain (eminently clonable), a pretty good nav system, a pretty good adaptive cruise control, no CarPlay or Android Auto, and no interior amenities worth mentioning. And they have absolutely terrible parasitic power consumption, a property that every other manufacturer has nailed for decades, because a car with a single lead-acid battery that parasitically discharges like a Tesla would be utterly useless. Tesla would like you to think they make the world’s best batteries, but they really don’t. They do have mindshare, though, and everyone else has been sitting on their butts and failing to compete effectively.
