In the end we have had since the 70's to realize that we did not have bottom less supply of oil.
Some may not remember that a few years go that even the Toyota Avalon had like 32 or 34 IIRC mpg. Transmissions can be tuned to deliver better milage. But no, we we wanted powerful SUV's and cars that gave us us less than 28 mpg.
I laugh at some "reviews" of my own Subaru Baja rated at 25mpg highway. Many reviews said they got only 22mpg highway. Guess what, keeping in 55 t0 70 mph on a straight highway shot - I get 29 mpg. I use the cruse control, when I can.
This even parallels my experiences on many rental cars. I have always been able to get 10% or better mpg over the EPA highway MPG, than what reviewers have stated. City MPG has met their limited reports on the such.
My worst MPG rating has been under sever "city" driving. And I still got 21MPG! Which was the MPG that I based my decision on. Much of my decision process on my purchase was based on the worst case situation. I get great pleasure at laughing at those that complain that it cost them $40 to $50 to fill up their SUV's.
I tell them I understand their pain. That I just spent almost $40 to fill up my tank. But this was for 18+ days of driving. When they so say, "well you drive so much less miles"; I tell them no, that I planned on gas prices going to $3 a gallon when choosing my car.
Love the stewing looks on their faces. When I am bitchy, I tell them that is the benefit of of having Depression Era parents that taught me not to take things for granted.
