You know that regulations have gone too far when the FDA has to regulate wheelchairs

This young man has helped design a computerized wheelchair that allows users to better control how the wheelchair operates.  It sound like a great idea.  But in listening to this piece at the WSJ I was surprised that the FDA had to approve the wheelchair before it could be produced.  Is the FDA soon going to regulate any type of chair that the disabled might sit in?  What happens if someone with disabilities sits in an unapproved chair?  Will the FDA SWAT team descend on the house?
