Sylvia has some good points.  Especially if you have children, because being 
a driver is so necessary to get those cute little non-drivers to their 
activities in a timely manner.  The lack of privacy is an issue if you have 
a blind or sighted spouse, but it sounds worse if your spouse is blind, 
because your joint privacy is violated.  I have to admit being driven to 
your wedding night, would take some of the romance out of it.
