thanks for all your tips.
i drove the car for another 30 commuting miles yesterday and today. seems the number gets better. 40mpg average.
then i reset consumption for the last 3 mile really jammed high way, turns out to be 70mpg.
the tip is that, dont step on gas unless you have to...
once the gas engine kicks in, the consumption goes up.
it will be a nice commuter car...

I am inclined to agree that you have to drive something like "the little old lady from Pasadena" to get close to 50 mpg, in the winter at least.
Since I live in Buffalo-NY, severe winters are a fact of life. For the 1700 miles I drove in February 2007, my mpg average was 47. For the 5955 miles I drove between May and September 2006 my mpg average was 57.
These figures are based upon filling the tank to the same exact level each time, i've found it impossible to rely on the fuel consumption trip gauge-it is sometimes 3mpg high,other times 3mpg low.
What are my secrets: disciplining myself to drive 60mph for 80% of my interstate drives. I save my 65mph stints for downhill and wind advantage stretches or when necessary to pass slower traffic. Since I do much nightime driving, this is really not as unreasonable as some might think.
The other is to maximize coasting/lower speed driving, so as to minimize full stops at traffic signals. It makes no sense to speed up only to have to come to a full stop-look ahead and try to predict when the traffic light will change. Anything you can do to minimize accelerating from full stops will in the long run improve your FE.

Actually, I have never been able to get less than 47mpg. I am able to average around 50, despite having to drive on the highway for more than 20mi of my daily 35mi commute. When I picked up the car in Kansas and drove to Oklahoma, and then on to Dallas, I drove on the highway at no less than 55 and no higher than 105 - I still got 51.3. This is confirmed by the onboard computer against my long hand. I chk'd the tire pressures before I left town and they were adjusted to stock pressures. However, the mileage did drop somewhat when I had to refuel in DFW with the 10% Ethanol blend mandated by the Fed/State. About 2mpg. Gas here is $2.769 if you hunt for it.

Thx for the tip, but what are the lessons involed in knowing the correct way of driving Prius -- pray tell... Thx!
