Front Seat Belt Anchorage problems of the 2000 Subaru Legacy

Seatbelts are too short for large people, resulting in inability to use them, subjecting owner and/or passengers to potential severe personal injury and/or consequent lawsuits. Dealer promises to provide seatbelt extenders since I purchased car last week, but I'm still waiting. My complaint is with Subaru for not making the original seatbelts long enough for all users; also with NHTSA for not requiring manufacturers to provide this most necessary safety equipment for people who weigh more than the 215 lbs. As is presently mandated by NHTSA. In my business, I often carry prospective home buyers in my car. Some of them are large, and most of them won't try to buckle up for fear they will be embarassed about the inability of the seatbelt to fit them. Rather than ask for a seatbelt extender, they simply say nothing, thereby exposing themselves as well as my other passengers (and myself) to further injury. Please, please, please expand the requirements for car manufacturers to meet americans' expanding waistlines! thank you.
