    That 1800 RPM is at zero MPH. Who cares? Put the darn thing in PARK.

    Uhm, a small fraction of the braking force available from the regular friction brakes?

    I don't hear about old fashioned non-ABS brakes flipping cars during lockup.

    OK, you are over my head here frankly.
    MG's = what?
    PSD = what?

    But in terms of the flipping of the car
    1) I thought he said he was afraid of blowing up the engine/transmission, not flipping the car?
    2) the Prius would be very hard to flip if you didn't go off road. It is a car, not a truck or SUV, which tend to flip easier. Plus a lot of its weight is low in the frame, which should, I would think, make it even less likely to flip than most cars. Even with a full on lockup of the wheels, the car shouldn't filp, unless he was corning hard. Might damage or even ruin the tires, wheels, axles, engine and/or transmission. But it shouldn't flip.

    think of the physics that would have to be involved to flip this car, even with the most severe of braking at the front. Especially end to end as you seem to suggest, as opposed to over on its side. The car has a very low center of gravity, and the battery pack in the rear, and a cabin full of people(wasn't it)? I just don't see it happening, even at highway speed. The tires might grind down and have a flat spot or even pop, but I just can't see it flipping end over end.

    I have taken "flip" to mean the rear end begins leading the front, as often happened to car prior to ABS.

    That would be 'spin'.

    Evidently you've never held the power button down for over 3 seconds, when the ICE is turning above 1800. Yes, it does work. ICE kills ... and your coasting begins.

    Provided everything works as designed......

    Only a few things need to work as designed. For any likely single point failure, and most of the most likely multiple failures, the kill function should still work.

    that would be a spin or fishtail or oversteer
