Well, most insurance is only for emergencies, and it is priced accordingly. For example, when I drove a car, I didn't have to deal with my auto insurance plan at all while getting gas or normal maintenance. However, when I got into a few bad accidents, the car insurance was vital for continuing to have a car, and it paid towards helping me get it fixed. Car insurance is insurance against something catastrophic happening to a vital part of life in most of America, not something to use everyday, and is priced accordingly.
Health insurance here is very different from car insurance. Rather than an emergency contingency, health insurance is woven into most healthcare purchases in the U.S. Accordingly, it is very expensive, limiting, and inefficient. Due to the dynamics of the system it creates, Americans must usually pay through the nose for even everyday healthcare without insurance.
If health insurance was operated more like car insurance, except of course that a human life should never be "totaled out," the system would eventually adjust and normalize.
