[DeTomaso] Seat belts

[asajay at asajay.com]

Okay, so I'm slacking here.  I'm looking up info on set belt and  
harness equipment for the Pantera (trying to prep for Silver State  
next year) and I come across this nice little disclaimer on Summit  
Racing's site:

"All seat belts are for off-road use only and are not U.S. DOT  
approved for street use. Summit Racing makes no representation or  
warranty regarding the ability of this product to protect against  
serious injury."

What the hell over?  So does that really mean your not supposed to use  
this kind of seat belt when you regularly drive on city streets and  
public highways?

Seems odd to me.
