Now fast forward 20 years and you can't buy a car insurance because you push too hard on the break.
Are you talking about the US? Because the ACA made that illegal years ago.* Your slippery slope hand-wringing doesn’t hold water.
*Under the ACA, premiums can only be based on three factors, IIRC: age, sex, and whether you’re a smoker. (And zip code.)
I'm not sure how that is in the US, but the abuse can come from anywhere and the result is likely to be worst that what they claim to be helping preventing.
> Health insurers can no longer charge more or deny coverage to you or your child because of a pre-existing health condition like asthma, diabetes, or cancer. They cannot limit benefits for that condition either. Once you have insurance, they can't refuse to cover treatment for your pre-existing condition.
I'm happy to see that is not the case in the US, but my was a general comment non necessary related to the US. But the fact that they're till law in the US presuppone that insurance company were behaving they way before.
