People shouldn't just worry about "no insurance" but also underinsurance. Minimal insurance in many areas is ridiculously too low. If you're signing up to do this as a driver you better #1 Tell your auto insurance company and #2 Up your insurance levels to the max (something you should probably do anyways if you can afford it).
If you're signing up to do this as a rider, well I don't think you should given the insurance problems and you not having any guarantee that someone will be held liable if they cause an accident.
Getting into a bad accident with an underinsured driver at fault is a life changing event.
Yeah. Perhaps my comment was not clear. They made it sound like you were in grave danger if you merely rode in the car of someone with insufficient automotive insurance, to which my answer is "make sure you have health insurance." Actually, that's my answer to many things.
