I'm like you "hayneda". My wife is also a Stay at home Mom, or Work at home Mom, I should say. We currently have 2 cars and every seldom are we using both of them at the same time.
I'm not commuting yet, but have been considering buying a nice bike for commuting (a recumbent) and getting rid of one of the cars. I'm going to have about a 13 mile one way commute, most of which is out of town riding.
Thanks for the info,
Dustin
