Tesla's lead is large enough that the established auto companies still (as far as I've seen) don't have compelling strategies for closing the gap.
As a technology company, Apple comes at the issue from a different perspective, and arguably, one with much more overlap to Musk, et al.
Batteries are notoriously difficult to innovate. We've seen story after story for more than an decade about breakthrough battery tech that doesn't or hasn't materialized, but the lead that Tesla has built has been by making a series of more-or-less incremental improvements to their design, coupled with the pricing benefits that come with the highest volume.
Do you believe that Apple has a battery technology that Tesla either is not aware of, or, is working on but not succeeded yet, or, has taken a look at and dismissed?
