" The point of insurance is that you pay slightly more than the expected value of your claims. "

Not true. Car liability insurance is very similar to health insurance. A lot of people never get anything out of it.

You don't have to own a car. Everyone gets sick at some point, and everybody dies of something. Whether that's cripplingly bankruptingly expensive or not is partly the point.

Although I suppose if the singularity happens, that will also solve the health care crisis in this country. (sarcasm)

Your EV from holding a car insurance plan is slightly lower than if you’d put that money in bonds. The benefit is that you can spread your risk across multiple parties. It’s entirely different from medical insurance, where your EV depends strongly on individual circumstances (and can be very negative). Medical insurance providers aren’t allowed to give accurate pricing, so you basically end up with a really complicated subsidy program.

Why are they not allowed to do so? I think it's more likely that they don't want to so they can make up prices as they wish.

This is exactly the same as health insurance. Spread risk over many people. EV depends on individual circumstances (driving skills or health). If health insurance is healthy people subsidizing sick people, then car insurance is good drivers subsidizing bad drivers. I don't see the difference.

But with auto insurance, if you're a bad driver, or even a driver with perceived higher risk (teen, unmarried, driving a little red sports car) your rates will be quite a bit higher. If you're a low risk driver, your rates are low. With ACA, if you are low risk (young and healthy) you are paying more than you would have otherwise.
They are using expected value in a technical sense.

In a pure contract between equally informed parties, it's exactly how insurance would be priced.
