How will the structural battery affect the ability to replace a car's battery relatively quickly?
If a battery expires within warranty, does the car have to go back to Maranello, er, Fremont for a total rebuild? Or will it still be a Service Center operation of a few hours?
The original S was designed with three-minute battery changes in mind (with appropriate heavy equipment to handle the battery packs during a swap operation, it's probably higher in actual time at an SC as opposed to the unused swap station.)
If Tesla has to "85" these new structural 4680-based packs some time down the road, and a battery swap requires shipping the car back to the factory, you can be guaranteed you'll never get your capacity/power/charging speeds back!
Maybe there will be some kind of jig designed to hold the new car together during a structural battery replacement to prevent issues during a replacement.
