Riding a motorized sofa down I-95 might seem like fun. But it's not safe. Or particularly legal.
For this, we can thank the National Highway Traffic Safety Administration.
(Seriously. We should thank them for this.)
The NHTSA, officially formed by the United States Department of Transportation in 1970, is the governing body when it comes to minimum safety performance requirements. These are the guidelines any car must follow in order to ride on federal roads.
The first such guideline for the Federal Motor Vehicle Safety Standards and Regulations was established in 1967, and it detailed requirements of "seat belt assemblies."
