My insulation contractor is unhappy because my house is doing lousy on the blower door test. So it goes. He'll try again in a few minutes.
Meanwhile, this is fascinating:
Vehicle Miles Travelled has been trending downward for the first time in decades--largely due to the Great Recession, but Levinson argues that there are structural changes that will create even more downward pressure on individual car trips. He doesn't cite public transportation--mainly because it is statistically minor, but I like to believe that improved bus service and increased rail service will eventually play a positive role.
I wonder if self-driving cars could have an upward pressure on VMT--people who can't or won't drive will suddenly be able to order a car to take them places instead of waiting for the robotic bus.
