>However, Musk claims that Tesla designed crash absorption rails that can be cut off and repaired to preserve the packs. Crash repairs are one thing, but what about complete replacement of the battery pack? if it's a major structural part of the car, are replacements even possible? and even if they are, would it be financially viable to do so? I know someone with a ~10 year old Toyota Prius who had to have the battery packs replaced and it cost them a few thousand in parts and labour, but that was designed to be fairly easily replaced (and the battery packs are a fairly small part of the car compared to those of an EV). If the batteries are non replaceable you've essentially made a disposable car with a 10-year working life. By comparison, my current ICE car is ~12 years old and less than 1/5th through the useful life of the engine. This is quite possibly one of the most decadent and completely wasteful things I've ever seen.
