Strongly disagree!!
While I think adding another "let's see if we can simulate another trip to grandma's house" kind of test would be pretty much useless, I'd very much like to see "pure" data as Carlos mentions.
EG. a chart of fuel economy plotted every X units from 50-120 km/h (30-70 mph) in top gear would be excellent for evaluating the efficiency performance of different vehicles.
Such as:
Tested: speed vs. MPG, 2008 Corvette Z06 (505 hp)

But I would like to know how they come up with the ratings. What is city? LA rush hour?

Here's how the EPA test cycles work:
CITY:
HWY:
They've twice added "fudge factors" to the actual numbers obtained from these test cycles. Also there are other, newer tests plus more detailed information about the above, here:
