Conserving time

I've only owned my second-hand insight for a couple weeks but I have no complaints.

I have enjoyed the tips for improving fuel economy on this site. (I've been a fan of the 50 psi tire setting for many years prior to my Insight purchase) I've read many accounts on this site about the high fuel economy that can be achieved by slowing down. I've heard many people going 55 mph on the highway or even slower.

So, I made some rough calculations to help me consider slowing down...

I drive about 130 mi per day. I compared 2 scenarios: #1) maintaining a average speed of 55 mph and returning 80 mpg. #2) maintaining a 72 mph average and returning 60 mpg. Some of you may think these numbers are high or low...perhaps you would do better or worse. But I just wanted a rough idea.

So assuming gas is $2.00 / gal... I calculated the money saved by slowing down: $1.08 ( per day by slowing from 72 to 55 mph)

Next I calculated the additional time required to make this slower commute: 33 minutes.

That works out to a return of $1.96 for an hour of my time. I realize getting high mpg numbers has become a bit of a hobby for some of you, so that enjoyment is neglected by this analysis. But does anyone really think this is worthwhile??

I plan to speed up.

"Not that I want to be the fastest, either."

Yeah. I aim for somewhere about the 80th percentile myself: somewhat above the limit, but still slow enough that there's likely to be someone going faster than me to catch the traffic cops' attention.

I perfer to save gas AND time by driving smoothly and planning ahead, for instance by timing traffic lights so I can roll through on the green, rather than (like some people) rushing up to a red, then standing on the brakes.

Well, I do think all of my time is of equal value, to me. Reality dictates that I have to spend some of it in obtaining the necessities of life (money, for simplicity), or the chores of daily living, like housecleaning, brushing my teeth, or driving places, but I would like to minimize those as much as possible.

As for the notion that by driving faster, I'm somehow spending my (hypothetical) grandchildren's inheritance, two points: First, even if I drove my Insight as fast as it would go all the time, I'd still be doing more than 99% of the population of this country. The amount of fuel &c I'd save by going 50 instead of 75 is miniscule in comparison to for instance that burned by cars without autostop idling at lights.

Second, if a person was really concerned, why not make an effort to drive less, by for instance getting a job within biking distance of home, or telecommuting?

Hey, can we leave out the politics, please? I, and probably some others here, disagree with the stated opinions re Iraq and oil, but you all know that if we get into it, someone will lock the thread :)

Besides, the difference between what an Insight burns going 55 and going 75 isn't all that much, probably what your average big SUV burns at idle.

If you're really concerned about saving gas, once again the solution isn't to try for the best possible mpg on your 100+ mile daily commute, or argue whether your time's worth more than the gas, it's to stop making that commute in the first place.

Yeah, and stop injecting your particular brand of unconnected-to-reality politics - at least 'till you can come back and tell us you've read the Koran and Hadith :)

'Course you're not as bad as some. My all-time favorite example of someone failing to connect their actions and their politics was the "No Blood for Oil" bumpersticker I saw on a brand new, still got temporary plates on, 12-mpg Cadillac SUV :)

"___I have to wonder what our little beauties are worth at an average speed of 80 mph w/ the auto-climate running the A/C as it sees fit?"

Well, I bought mine from a guy in Las Vegas, and drove it back the 450 or so miles on a fairly hot day in late May/early June. Averaged around 80 (touching 100 in a couple of places), with A/C on (and not econo mode, as I hadn't figured it out yet). Still got about 55 mpg :)

"If you are burning up an extra ½ gallon in your Insight day over day..."

But isn't that just as good an argument, if not better, for finding a way not to make that long drive in the first place? Instead of saving 1/2 gallon and 30 minutes per day by driving 50 instead of 70, you'd save 2+ gallons and maybe 3 hours per day :)

"If the ME were non-existent, would we need a US military as large as it is?"

(Sigh) Politics again, and I can't hold back much longer :) I really, really wish that some people would disabuse themselves of this notion that history only began a couple of years ago, or maybe in 1945 at the earliest :)

xcel: "In other words, should we all work at the local McDonalds for ¼ as much with little to no benefits and not drive..."

I think you misunderstood my point. I certainly understand your decision to drive further so you can make more money, but what I don't think you're seeing is that it's really the same logic as the people who drive faster in order to save time. We're all trading a bit of extra gas use for things that are of more value to us, whether it be higher pay or more free time.

After all, how can I quarrel with your 90-odd mile commute, when I just took a job that's about 7000 miles away :)
