This is clearly an important factor in determining your vehicles fuel consumption, but it's pretty difficult to make quantitative estimates and without it comparisons are pretty meaningless.
My car's computer can tell the average speed since the last reset (i.e. re-fueling). And it's always suprisingly low! I use this to estimate the %City driving by assuming it to be a linear function of speed from 20km/h=100%City to 120km/h=100%Highway. [more inside]
