In my opinion the GVWR rating is more about safety and long term reliability of the vehicle. How does overloading effect braking distance? Running overloaded all the time certainly would reduce component life and could cause premature failure. An occasional overload I really don't think is a big issue as long as caution is used. Of course the GVWR comes into play when you're talking commercial vehicles but that another story. The NHTSA requires these stickers on vehicles, it's up to the consumer to use common sense which is the problem.
I agree GVWR does serve a purpose. If you are buying a grocery getter it is relatively unimportant. If you are buying a tow vehicle you want to be concerned with the GVW and how it impacts the towing parameters.
Exceeding GVW occasionally will have minimal effect exceed GVW regularly will result in premature wear down the road. BTDT.
