If there's injury, $30k would only cover a day or two in the hospital, might not even cover ER expenses, as they'll be charged at list price not the "negotiated" rates insurance companies pay.
$30k is an absurdly small bond to post for self-insurance, though I'd believe that the regulations have not kept pace with reality.
The cash rate is similar to insurance negotiated rates. Typically 25-30% off automatically, 50-100% off with a financial aid application. Doesn’t change the inadequacy of $30k medical liability in a serious wreck, but don’t think you’re stuck with list price bills if you’re hit by an underinsured driver and have no health insurance.
