Doing the math

I found this image on the PedNet website and love the way it conveys an 

important truth in a simple yet profound way. I was biking across town 

the other day and was amazed at how many cars only had one driver in

them. What will it take, gas prices at $10/gal to get us to choose smarter 

alternatives? More importantly, what about those citizens of Columbia

who simply cannot afford a car? All those people working at Walmart,

Target, the grocery store, gas station, etc who make our worlds go around

and yet cannot get inexpensive, efficient transportation to that $7/hr job?

Just a thought.
