you are so willing to jump on anything someone posts that 'could' support you.
what is the capacity of this electric driven pump?
considering the Prius is all about efficiency, it probably isn't designed for over capacity.
look at it this way, do you think a Prius a/c compressor could work in a Sequoia?

Right, and if you let up on the brake pedal because the car wasn't slowing down fast enough, it would cause even more heat to build up in the system.

Your Prius will not lose braking assistance at WOT. The vacuum is provided by an electrically driven pump.
 
I'm even more surprised the hybrids don't have a smart pedal, since left-foot braking is detrimental to fuel efficiency. I'm guessing that, on a hybrid, the first bit of brake pedal travel only activates the regenerative braking system and not the disc brakes.

Would it work? Yes. Would a compressor designed for a midsize car be adequate for a fullsize SUV? No.
 
What's your point?

my point is a piece of equipment designed for normal operation, may not work as expected under extreme circumstances.
just because it is electric does not mean much.

No, my company bought a 2010 LaCrosse and I looked at the hard copy. Haven't had a chance to drive it, though.

The ignition key is the tried and true method, but pushbutton ignition switches have become common in higher end cars and in hybrids like the Prius.
 
Even if you have a separate kill switch (off button), it has to be designed so that it can't be accidentally hit while driving. I would imagine some kind of recessed design would help, AND you might have to hold down the button for 1/2 to 1 second.
 
As far as I know, only Audi has separate on and off buttons; does anyone out there know how the off button functions while the car is in motion?

I thought I had posted this reply but don't see it.
 
If I had a situation of unanticipated WOT, I agree that shifting to neutral is an option, albeit a very expensive one that we all know will self destruct the engine in short order. It would cost thousands of dollars. It would be something that many would delay doing until it might be too late and that would lead to a bad outcome. Secondly the self destruction of the engine would also lead to loss of of all power assists so we are back to square one. I've driven cars that unexpectedly lost power and it does require concentration and effort to steer and apply brakes but it is still feasible.
 
Under no circumstances should either a familiar or unfamiliar driver be put in a position where they do not know how to shut down the engine immediately.
 
Toyota somehow missed the boat to provide a commonsensical solution to this problem that would save dollars and lives and that is the need for an obvious labeled kill switch that is accessible to drivers and passengers.
 
We can discuss the need for powerful brakes and in place floor mats but the obvious first need to any unforeseen circumstance is the ability to shut down the car.

Not sure where you got your info, but modern cars have rev limiters. You can put your foot to the floor in Park or Neutral and they won't go much over the redline. Some cars won't exceed 4,000 rpm when the transmission is in Park or Neutral.
