Sure sounds suspicious.
It is hard to troubleshoot on somebody else's observations.
The memo did say that investigators found the front brake pads were spent.
"Visually checking the brake pads and rotor it was clearly visible that there was nothing left," it said.
The rear brake pads had 1/2 mm left, or 3 1/2 mm less than new pads, the memo said.
That doesn't sound to me inconsistent with the computer going off into neverland and ignoring all inputs , like Windows does-
referring to that Prius brake system diagram a few posts back:
the SLxxx solenoids apply braking under computer control and if computer is off chasing a loop someplace he'd lose normal brakes.
The SMC solenoids allow front wheel braking only in emergencies when computer has failed or power is lost. Presumably they're on a 'Dead Man Timer' which, if computer doesn't pay them frequent attention as in program failure, opens the SMC valves. That connects master cylinder directly to wheel cylinders for "limp home mode" brakes.
Limp Home mode would require a LOT of brake pedal force to slow the car because there's no boost from the reservoir - SL valves are closed. He reported standing on the pedal. Limp home would not apply the rear brakes, which had a teensy bit of lining left about twenty thousandths of an inch.
Computer got a power down and restart when he stopped the car, and certainly again when they removed it from the car for NTSC investigator. So if something did throw program into a tight loop it's gone with the e-wind.
....What the heck does this mean?
The brakes on the Prius also did not show wear consistent with having been applied at full force at high speeds for a long period,
That's somebody's opinion about their observation and they didn't bother to describe what they saw.
Reporters are real frustrating.
So who knows?
To me the question is how'd the back wheel brake linings get so worn out in a car only a year old?
Maybe you're right and he's been practicing for this...... realtor + lawyer + $$$ = monkey business???
and there's this from the practical Canadians:

Runaway Prius story more fiction than fact
If this phenomenon is real some hobbyist who's hooked his laptop to his car's Canbus port will soon capture a runaway event and put it on Youtube.http://www.vassfamily.net/ToyotaPrius/CAN/cindex.html
