I cringe everytime I hear people yell about SUVs and their gas mileage. I was talking to a friend of mine in California who made some pretty...militant remarks about people who drive SUVs and their irresponsible behavior. To which I said, "Wait, don't you commute an hour per day to work?" To which he said, "Well sure, but I drive a Toyota Corolla." So what?
I don't care what kind of car you're driving, if you're driving over an hour (total) per day, you're burning a lot of gas. Some people have to drive that far and other people simply prefer to live out in the country. And I have no problem with that. But if you do live far away from work (or in the case of my friend simply have to drive through heavy traffic for long periods of time) then you can't go around condemning other people's car choices.
I don't have an SUV. But I do have a car that only gets 18 miles to the gallon. I also drive 6 miles to work and 6 miles home. I spend about 20 minutes per day on the road -- total.
The Corolla gets around 35MPG on average if you're driving it mostly in the city. My friend drives about 25 miles each way, 50 miles per day. So he burns 1.43 gallons of gas per day. I burn 0.67 gallons of gas per day. Over the course of the year, he uses over 500 gallons of gas. I use 243 gallons of gas -- less than half as much.
I don't care what kind of car other people drive. But if you're going to take on a holier-than-thou attitude on fuel standards, then you better be factoring in your commute distance.
