The whole point is that in every other car everyone else has driven, the
gas gauge may have been off--but it was *reliably* off.

The bladder in the Prius tank means that you can't predict what the
gauge actually means, and that's way different than people are used to.

Well, let's see.  The flashing pip told you the engine would quit within
70 miles.  Regardless of how much you put in vs. what the stated tank
capacity is, I'd say the gas gauge was pretty damned accurate in
predicting that you're an idiot.

Look everyone.  It's the "I don't wave" guy.  He has awarded himself a
better nickname: "The Flashing Pip."

Lets restate what happened for those who can not (or will not) read.

3 times I drove 20 to 70 miles on flashing fuel warning and bought less
than 10 gallons. Gauge is now calibrated and behavior believed to be

A few weeks later the light started flashing and ONE MILE later the ICE
was dead. The gauge was taking measure of fools who trust it. Yes, the
light said the engine might run as long as 70 miles based on past
experience, but 1 mile isn't any warning at all. And 1 mile sometimes,
70 miles sometimes, isn't very reliable.

I continued my analysis and concluded the gauge falls about 1 to 2
gallons slower than actual (miserly) consumption. Let it sit over night
and the gauge catches up. This is normal for ANY CAR, and no other car
than the Prius has a bladder gas tank so its not a bladder thing.

The only thing different is that most cars use a thermistor in the gas
tank for the low fuel warning light. This thermistor is very accurate,
fast, and reliable. Apparently the Prius does not use a thermistor.

Why wait past 1 pip?  Why wait for the flashing light at all?

Why not buy gas at 2 pips?  3?  What are you trying to prove?
