There are people who have attempted to get battery replacements for the early model Teslas and the price was either inanely high or most of the time unavailable. For all intents and purposes, I interpret this as the car is not meant to be serviced or repaired long term and therefore disposable.

Granted this is not exclusive to EVs. Most ICE vehicles made in the last 10 years have or will be affected by unavailable parts or worse, serialized parts. Much like FutureMotion's Onewheel that Louis Rossmann has been covering, even if third parties are willing to make aftermarket parts, they either can't bypass the DRM or if they do they will be sued into oblivion. Both EV and ICE cars are heading this way and it's a environmental disaster.
