This horse was beat to death at Volokh Conspiracy over a editorial about Michigan that cited VPC.
I'll repeat the arguments I made there. Using the WISQARS statistics for 2009 Michigan (962 accidental motor vehicle deaths, 12 accidental gun deaths, 572 gun suicides, 495 gun homicides):
The relevant product safety stats are the accidental deaths: 962 accidental motor vehicle deaths versus 12 accidental gun deaths. Consumer product safety regulation can have an impact on accidental deaths. Do those numbers represent a product safety problem with guns?
Intentional deaths are the result of the lethal intentions of those who commit homicide or suicide with firearms. Look at it this way: would federal product safety regulation impact intentional deaths (suicides or homicides) with motor vehicles? Do airbags or seat belts prevent deliberate vehicular homicides?
Criminologist Marvin Wolfgang (who personally hated guns) studied 588 homicides in depth and concluded that few homicides due to shooting would be avoided in the absence of the gun. Motive and opportunity determined the outcome more than the presence or absence of a given means. The same has been observed in suicides by restricting various means.
ADDED: What I suspect VPC is shooting for is Consumer Product Safety laws that would say, for example, if a revolver or lever action rifle does not have manual safety switch or crossbolt, it will be condemned as "unsafe at any range" and ordered confiscated and destroyed in the name of safety.
