I've got plenty of gripes with Musk -- not the least of which are Tesla's marketing of assistive driving technologies, which the folks there had to know would be misleading.

I think this is somewhat unfair, though: that $10k is for a software unlock. Battery tech is hardware. Toyota can't charge extra for advanced batteries before said batteries are ready for mass production, for obvious reasons -- so they didn't really have the opportunity to engage in this kind of broken promise.
