Will the Real Environmentalist Please Stand Up?
Saturday, November 21st, 2009I rarely speed. It’s not that I’m particularly law abiding or that I’m intentionally conserving fossil fuels. It’s partially that I know the extra 10 mph won’t make much of a difference in my drive time. But, mostly, it’s that as a freelance writer, I am constantly broke. So, I can’t afford a moving violation (or even a parking ticket for that matter). Now, because I do drive the speed limit, I am keenly aware of all the super agressive driving around me. At times, I’m even the victim of that agression. So, I wasn’t surprised when a guy came whipping up behind me in the slow lane on Soldier’s Field Road, made an aggressive move to get around me, shot me a dirty look and then sped far ahead. However, I was a little surprised and particularly amused that the guy was driving a Toyota Prius.
It would seem to me that the main reason people buy hybrid cars is for the better gas mileage. The reasons people want better gas mileage is to reduce their “carbon footprint” and cut costs. Many of my composting, recycling, solar panel owning, MASSPIRG volunteering friends drive them. Anyway, it got me thinking about whether an aggressive hybrid driver is more damaging to the environment than a non-aggressive driver of a regular car–thus my amusement.

After researching a little bit, I was delighted to find this Edmunds article discussing fuel efficiency. According to their test results, non-aggressive drivers save 31% on milieage on average; non-speeders save an additional 12%. So, the Prius guy that slammed on his brakes, whipped around me and then stepped on the gas again potentially burns over 40% more fuel while only saving about 20% due to the environment friendliness of his car. Thus, the guy may still burn 20% more fuel than a guy with a regular old Ford Focus or something.
The author of the article even mentions hybrids in discussing the results:
Our tests showed that the most significant way to save gas is: you. And we’re talking massive fuel economy gains. Think you need a hybrid? Chances are you’ve got hybrid-style mileage in your gas pedal foot.
