    •  Those Cars Aren't Really 30 Or 40 MPG..... (4+ / 0-)

      Even though they had claims of it being 30 or 40 mpg when they were sold, until recently the EPA tests didn't simulate real-world driving. That's why if you go on YouTube, you can find a bunch of old car commercials claiming outrageous fuel efficiency stats. Add into this that anything from 20 or 30 years ago is also going to put out more emissions than current models.

      There's also the factors of weight from standard features on present-day cars that weren't on the old cars. That Civic, Tercel, and Toyota pickup might have had (flawed) high mpg numbers, but I doubt it had driver & passenger air bags, let alone side impact airbags. It didn't have traction control, anti-lock brakes, or a host of other safety systems that are standard issue on modern automobiles. All of those things add weight, and decrease fuel efficiency.
