How exactly would you completely drain the battery-pack?
 
The system has quite a few protective mechanisms preventing that from ever happening.

Let us say a malfunction.

Any component in a vehicle can malfunction.
 
Unless there is more than just a remote possibility of it actually ever happening, discussing it doesn't have a point.
 
In other words, there is a higher statistical chance of being in an accident. So why focus on someless even less probable?

Most people are wary of electrical systems in a hybrid, and how it interfaces with the rest of the drive train, than they are of any other system. So, it is logical to bring up that probability.
 
But, my point was to bring out a scenario where electric supply fails for a moment. Would the gasoline engine be able to move Prius by itself?

Toyota's Hybrid Synergy Drive is the most advanced automobile technology ever created. If I recall, the Prius (and all HSD vehicles) are equipped with at least five computers on-board to make constant calculations and adjustments. For all practical purposes, Toyota's hybrids (and now Ford's, as they're using the 1st generation Toyota technology), are supercomputers on wheels.
 
Now, should the "electrical system" fail, what can you expect? Your car is broken. I speculate (though certainly can't confirm) that you can't drive because the car has an eCTV (electronically-controlled continually variable transmission). This isn't something to worry about, though. We're not talking artificial intelligence here, capable of destructing the world if it gets out of control... it's still a car. You should be more worried about a flat tire.

If valid, this would answer stevedebi’s question.

Ah, almost forgot.
 
Should you decide you're not giving Shell one more cent of your money and run out of gas, the batter and motor are capable of propelling you for a short distance. Of course, this isn't good for the car but I have heard stories of Prius owners gliding into the gas station in purely electric mode.

No, it doesn't really. I still think his question is about the equivalent to "If the gas all of a sudden magically disappears from the tank of my F-150..."

Hmmm, considering the MPG of the F150, doesn't gas always magically disappear from the tank. You look down at the dash and - WHAM - there is the low fuel light...

We are making this hybrid 'thing' way more complacated than it needs to be ...
 
How a Honda employee bakes a potato:
Preheat new, high-quality oven to 350 F. Insert Idaho potato. Go do
something productive for 45 minutes. Check for doneness, and then remove
perfectly baked potato from oven and serve.
 
How a GM employee bakes a potato:
Instruct an Idaho potato supplier to preheat the oven to 350 F. Demand that
the supplier show you how he turned the dial to reach 350F, and have him
come up with documentation from the oven manufacturer proving that it was
calibrated properly. Review documentation, then have supplier check the
temperature using sophisticated temperature probe. Direct supplier to
insert potato and set timer for 45 minutes. Have supplier open oven to prove
potato has been installed correctly, and request a study proving that
45 minutes is the ideal time to bake a potato of this size.
 
Check potato for doneness after 10 minutes.
 
Check potato for doneness after 11 minutes.
 
Check potato for doneness after 12 minutes.
 
Become impatient with supplier (why is this simple potato taking so long to
bake?). Demand status reports every five minutes. Check potato for doneness
after 15 minutes... After 35 minutes, conclude that potato is nearing
completion. Congratulate supplier, and then update your boss on all the
great work you've done, despite having to work with such an uncooperative
supplier. Remove potato from oven after 40 minutes of baking, as a cost
savings; without loss of function or quality versus the original 45 minute
baking time. Serve potato.
 
Wonder aloud what on earth those Japanese folks are doing over there to make
such good low-cost baked potatoes that people seem to like better than GM
potatoes.
 
Daimler Chrysler's Baked Potatoes:
Design great looking potato. Include sour cream, bacon bits, chives, and
cheese. Bean counters then create MCM system. Engineers spend 2 years
looking for ways to take out sour cream, bacon bits, chives, and cheese.
Engineers find cheap imitation chives from Japanese supplier. Management
commands engineers to use expensive, over-engineered German bacon bits to
help prop up weak German suppliers. Sell potato with cheap imitation chives,
no sour cream, cheese or expensive German bacon bits. Potato rots so fast
customer swears never to buy another DCX potato.
 
Ford's Baked Potatoes:
Engineers create plain looking, "everyman" potato. Sold as "green"
alternative to French Fries. When micro waved, potato explodes, causing
death and injury to customers and bringing end to 100-year potato and
butter-supplier relationship, lawyers flourish.
