Word came down yesterday that Portland has ranked in a survey as having the most courteous drivers in the country.
A piece I heard on OPB opined that this was because we had shorter commutes and were thus less frustrated. Let me take that a step further and hypothesize a link from have having lower VMT per capita (or that VMT per capita is level or decreasing) makes us happier and less confrontational on the roads (I admit to having no data to support this hypothesis).
What do we think? Is the rain, something in the water? Is it driving less?
