This seems like a strange move on Teslas part.
Insurance is a business of quantifying risk, charging people appropriately and making your money by investing those sums before claims are paid out.
That doesn't seem like a great fit for Tesla. They cant reasonably invest all that money in Tesla and Tesla bonds, Tesla just becomes a confusing story of car maker and insurance that won't be greater than the sum of its parts.
As others have mentioned, prices indicate this isn't some Muskian disruption of the market so why the distraction? Am I looking for reason in what is intended to be a nice little earner on the side?
