re: 2) yes that was the point. She'd have to be paying multiple thousands in an assigned-risk pool policy with that record of at-faults.
The victim's own insurance will pay if they have uninsured motorist coverage (you'd be a fool not to have it, living in LA at least), but there is basically no punishment for the uninsured driver, assuming a fender-bender. The police won't do anything. The insurance companies don't think it's worth their time to try to squeeze out something from someone who probably has almost nothing anyway.
In almost every state, you may post a bond in lieu of insurance, for an amount as low as $35,000!
Most of those state processes are a) reserved for businesses b) discretionary and they exercise their discretion not to approve anyone.
If it was something that was practically doable every 200k HHI household that drives old cars and has good health insurance would take advantage of them.
