> 1. invest money in a supply chain to have parts in stock for the battery assembly(take many months). They already have this for other parts, it's trivial to extend the model to the battery. The problem is that the battery was not designed to be serviced without specialized tooling and expertise. It doesn't have to be that way. It was their choice. They made that choice because it costs them less money to service the batteries in bulk at a specialized facility, at the expense of the customer. It's not like the customer has a choice. They already bought the car. What are they going to do? Here is another option: 4. Design your vehicles in a way where a $1 part can be easily detached and replaced by anyone with basic tooling, instead of charging the customer $18k for a new battery. This isn't just an issue with Tesla. This is an issue with almost all manufacturers today. They make more money when they replace the entire assembly. Apple operates in the same way. If one of the keys breaks on your laptop, Apple will replace half the laptop. That's the only option. You can't replace the key. It was designed this way.
