Speaking of the auto industry, Amy Alkon points us to a proposed NHTSA rule that would add $2.7 billion to the price of automobiles to make it slightly less likely that careless parents will back over their children: mandatory rear-view cameras. Of course, even without the NHTSA regulation, it's only a matter of time before product liability lawyers allege that the failure to include such cameras is a defect and that auto manufacturers should be assessed punitive damages for failing to prevent a bad driver from backing over his or her child.
