Really this is a hard post for me to write, talk about being a hypocrite. Since I literally have a foot made out of lead, since I have 9 to 10 (you sort of lose count after a while (I think the cops have only threatened to arrest me once or twice, again who is counting)) tickets, and since I think I have some freak gene (this is self diagnosed there is no scientific evidence to back this one up, but I think we all know I have a freak gene somewhere in me) that makes me do it, driving the speed limit is a challenge. But as I am always looking for ways that I can help better serve the planet I thought I would give it a try.
OK so really since we had our son I have slowed down a lot in the car. I mean there are obvious safety reasons for going (at least somewhere close to) the speed limit. But as this blog is dedicated to environmentalism, today we will focus on the environmental benefits for driving at the designated speeds. So let me try and break down some of what I understand to be reasons why driving the speed limit help. You brake less. That is a good thing, each time you have to break (or weave, or whatever you do) to slow down because you are speeding you are reducing the fuel efficiency of the car. You are also have less air resistance as you go slower which reduces drag. Pretty sure that right about now I should segue into some very complex physic based explanation, but instead I will totally cheat and offer a few sites that may help explain a little bit better http://www.fueleconomy.gov/feg/driveHabits.shtml and http://www.gao.gov/products/GAO-09-153R.
One thing I can say please never let your car run or idle if you are not driving. If you are stopped on a driveway in a parking lot, stop the car. Running the AC or whatever else you may require is just not worth it. Turn the car off think about what running the car is doing, oh yeah releasing lot of lovely CO2.
So I am going to end here. Even if you do it for safety reasons alone, that is good enough for me. And I will continue to improve my speed limit skills, and practice this common sense, easy, and semi-free (minus the cost of the actual car and gasoline) approach to protecting the environment.
