Agree with Pix. Costs can always come down on a new technology. Remember when hybrids cost $10k more than a standard ICE? Battery sizes for hybrids haven't changed but yet overall system cost has come down significantly to the point where it is about $1500 more for the hybrid model compared to the non-hybrid.

As alluded to in the article, if Tesla can make this happen, yes, it will lower the initial cost/sale price. But due to extra costs associated in replacing such a large component in any significant accident, the insurance for that car will be substantially higher. For the consumer who buys this vehicle, it will probably be a marginal total cost savings. Save $5k upfront to only pay $500-$1000 more per year in car insurance.

While true for the very short future, the body's cost is not trivial, and when trying to hit a particular price point not orders of magnitude lower than existing models every bit counts. Likewise, the battery is not a "fixed" cost between models. Different battery sizes with different material costs can make a large difference, especially in a comparison between a Model X Extended Range and something like a Model 3 with the standard range battery. New chemistries and electrolyte configurations (Sodium-Ion batteries, Solid State batteries, etc.) are also on the horizon for many battery suppliers and are even making early production appearances in some smaller brands' EVs.
