Drunk driving. Don’t do it.
Besides all the obvious reasons here is one more to add to your list. All health insurance policies have provisions that allow them to deny claims that fall in to certain categories. The majority of the denials have to do with procedures that are not medically necessary. These would be things such as plastic surgery to reshape your body or face for the simple reason that you don’t like what you see in the mirror. There are also denials of benefits for intentional self inflicted injury, whether sane or insane; and there is denial of benefits for injury sustained while committing a felony.
Most people think of this as getting shot while robbing a liquor store. That will certainly qualify but that is not the only felony situation.
How about accidental overdose while using Class A narcotics? In many jurisdictions simple possession of drug paraphernalia is a felony.
So is DUI.
In some places a DUI alone is a felony. In most places, if someone else is injured or killed, that will almost certainly lead to felony charges.
A felony conviction can result in denial of your health insurance benefits.
Think about it.
