> ultimately it's an implementation detail

Impressive engineering is always about details.

If you want to argue that there is really nothing superior about Tesla's engineering that's fine, but you can't shove implementation details under the rug when it suits you. For there to be nothing superior in their engineering there must also be no implementation detail that is superior.

My "implementation detail" comment above does not refer to the quality of engineering overall, but specifically in the context of competition. Yes, when comparing electric cars, the quality of the electric engine is a very large element; but it is much smaller if we're comparing all the elements that matter to someone buying a car (quality of body construction, interior finishing, steering etc).
