Personally, i want higher prices. Why? i live in a uber croweded city where even the Dogs would have cars.

The number of cars isnt the only rant, but, i'll see a lot of cars on the street with expired TAGS. This pisses me off. Means they dont have INS.

You cant renew your regs without proof of ins.

High prices would mean more public transportation and less idiots like that on the road.

All these people chanting "Yay high gas prices!" greatly disturb me.

Whoa, you're got your math wrong there!!!

Really? 12,000miles divided by 15mpg = 800 gallons per year
12,000 miles divided by 30mpg = 400 gallons per year.

That saves 400 gallons per year.

12,000 miles divided by 12,000mpg = 1 gallon per year (obviously) - a savings of only 399 more gallons. So, the 15 to 30mpg jump saves more gas than a 30 to 12,000mpg jump would.

Well, you are indeed correct....but you still "use" 3,900% more. Maybe gallons per mile does make more sense than miles per gallon.

Why didn't you just list the numbers as percentages? I think that would have made more sense in your justification. Going from 15 to 21 is a 40% increase while going from 39 to 51 is only a 31% increase.

Just makes it easier to follow your argument.

Since you used the word "only" in front of 31% increase, it's apparent that you didn't understand the argument either. Going from 27 to 51 is a 67% increase, while going from 15 to 21 is "only" a 40% increase. That's what people see and think, and they're absolutely wrong. That 40% increase saves more gas than that 67% increase.

It saves more going from one class to the next, but it "still" uses more than those in the upper mpg classes.

I agree with you that everyone should work on saving gas. However, not everyone can give up their truck or vehicle in certain classes in favor of vehicles in other classes. A family with 3 children isn't going to have a family car that gets 51mpg. My point is simply that people can't deal with numbers and can't rank the gas savings relatively.

Assuming 12,000miles per year, I think a lot of people would have a hard time believing that going from 15mpg to 30mpg saves more gas than going 30mpg to 12,000 mpg.
(29.9625mpg is the even point, if my math is correct.)

How common is it for a family to have 2 cars which they put an equal number of miles on each (12,000 no less)? One could argue that if they went with the car with 51mpg, they would use the truck only when necessary, and shift the mileage distribution to, say, 6,000/18,000 in favor of the car - in which case the hybrid is worth it.

I get that 12,000 is the average, and I definitely agree that simple maintenance to get an extra 2-3mpg out of your car/truck is incredibly practical, but ultimately a change in consumption far outweighs mpg ratings.

There's a huge ripple effect of prices across the economy. Higher fuel costs are going to mean higher costs for a LOT of products. Rather than wish for higher fuel prices, wouldn't it be better to wish for police who would ticket and eventually tow those vehicles with expired tags?

Maybe someone should plug this stuff into an Excel sheet

Yes, it uses more than the 51mpg option, but you are forgetting one of the constraints listed in the original post: The husband, for whatever reason, requires the truck. There is no option for the couple to be without a truck.

So moving from the truck to the hypothetical 51mpg Hybrid isn't a possibility, or rather, it's technically a possibility, but it's not a viable one.

That's where "hydraulic hybrids" enter the picture!

LOL. The one forgotten item in this equation is that if everyone went from 30 mpg to 12,000 mpg, gas would fall to $0.50 per gallon instead of the $4.00+ per gallon and you would save far more! (j/k but true to some extent).

You need to sit in on an Engineering managers meeting on new equipment for a short while...your brain would really be broke then!

 

[imported_Baloo]

Yeah, there's an article on CNN from the Associated Press about this very topic here I'm sure this is where you got the idea for your post; You ripped the entire article without a word of credit to the writer.

If his work requires him to drive a truck wouldn't it pay for his gas anyway?

Maybe he is a "self employeed" contractor (lawn service, home repair, etc.).

Even still then his "business" is paying for the gas in the long run.

My car gets better mpg then the not so "Smart Cars" and takes regular unleaded as well.

Going from a 15mpg SUV to a 51mpg hybrid saves 564.7 gallons too. Sure, going from one to class up to another might not be as much as going from 45 to 51, but remember, they are still getting above 45 and you're now getting 21. Unless somebody comes up with something quick, we're still running out of the stuff at some point (the algae that shits crude oil looks nice though! ).

It makes sense to save as much as you can as long as you're purchasing a vehicle anyway. It does not make sense to rush out and buy a car (usually) just to save gas.

Once again, the engineer exposes the mathamatician's flaw

it wasnt a flaw, it was stated that the truck was needed for whatever reason, and would continue to be a truck regardless of the outcome. so, in that case, going to a truck that gets 21mpg was the better choice. of course replacing a 15mpg truck with a 51mpg hybrid car would be the optimum, but not necessarily the realistic outcome.

And this would be an argument against the hybrid since company (contractor) gas is tax deductable.
Suppose the husband's highest tax bracket is 30%. He purchased $10,000 worth of gasoline that year. Since he isn't supposed to pay income tax on that gasoline money, he gets a writeoff for 30% of $10,000 which would be $3,000.
If you pay $4.00/gallon at the pump, that contractor is effectively paying $2.80/gallon (70% of that).

When the family hybrid car is using tax-free gasoline (all small business pull this), then it's really hard to justify spending an extra $10,000 for the hybrid model. If it was a very high mileage company car, or a moderately high mileage not-company car, then the hybrid might really be worth it.

With the falling prices of SUVs/trucks, it would probably be better just to hold on to a gas guzzler because you're not going to get a very good trade in value when you buy a new car.

It's great that consumer demand is finally going toward fuel efficient vehicles and that the car companies are finally listening. However, it's causing major problems with food costs.

 

[TXHokie]

I would pay more for a hybrid car built here and send less of my money to the M.E. for gas.

I know for this example it's a given that the truck is required, but honestly 8 or 9 out of every 10 people who claim they "need" a truck don't actually need one.

where does my bicycle fit into the equation?

Sooo... replace "needs" for "wants" and the argument remains valid.

Well, as you get 0 gallons per mile (or 0 miles per gallon, if you prefer) any vehicle is a huge improvement as far as gas mileage goes.
