Also, med-pay is important if your state has it. It is money to cover your medicals. You can use it just for your out of pockets (copays/deductibles) or use it instead of health insurance. Unlike health insurance, it doesn't get paid back from any settlement/judgment so it reduces your lien amounts.
The different in price in my policy to go from 1000 medpay to 10,000 medpay was minuscule.
I have to disagree with this. The number one rule of insurance is that the insurance company will make a profit. Therefore you should only buy coverage for things you wouldn't be able to pay for out of pocket. I already buy medical insurance to pay my medical bills. I chose a medical plan with a deductible that I'm willing and able to pay if something bad happens. A car crash is one of dozens of reasonably likely things that could cause me to use up my medical deductible. Why should I pay extra for an insurance that pays this cost in the case of a car crash, when I'm able to pay this cost myself in the case of cancer, heart attack, injuries related to athletic or home improvement activities, etc.?
First, I also want to mention that in many states, your car insurance covers you while you are biking or a pedestrian too so if you get hit by someone under or uninsured you have coverage.
On the medpay issue, let me give you an example. The issue isn't that your health insurance won't cover you but rather that they would have to be paid back out of any judgment or settlement. Medpay would not have to be paid back. Also, the cost of adding it is generally very low for the benefit. As to whether you would rather self-insure that risk, you can look at the cost and decide.
Here's the example. You get in a car crash and have $10,000 of medical bills. With your health insurance's contracted rates, they pay $6,000. You also pay $1,000 in copay/deductibles. You have some pain and suffering but no lost wages. Your claim settles for $30,000. $10,000 goes to your lawyer. $6,000 goes back to your health insurance. You get $14,000. Since you already paid $1,000 in copays you are only getting $13,000 new money in your pocket.
Let's say you had $10,000 in medpay. Medpay covers all $10,000 of your medicals. Claim settles for $30,000. Your lawyer gets $10,000. You get $20,000 in your pocket since you don't have to pay back any health insurance company and you had no out of pocket loss.
