Just picked this up off of the old forum from dwilson. I believe it is what most of us expected.
My sister was the person killed in this accident and she WAS wearing her seat belt! In fact, the seat belt is what caused my sister's death and it was also the cause of the critical injuries to her husband (the driver). For all you Polaris Slingshot owners I would recommend you DEMAND a 4-point harness type seat belt in these vehicles! My sister's main artery was severed from the seat belt. Even a go-chart has a 4-pt harness for extra safety. Don't thing a regular seat belt is going to save you from injury but it won't. I truly believe if they had this type of seat belt, my sister would be alive today.
I pray to God you ALL move forward in DEMANDING a different seat belt design!!!! I hope some how this information helps you.
