At WFO the engine doesn't pull any vacuum- If he pumped them (which
would be a natural thing to do) he would have wasted all the reserve
vacuum in the vacuum booster.

It's also possible that he applied them insufficiently at first, used
them to maintain speed vs. stop right-freakin-now and they faded into
uselessness.

That sounds much more like the Audi "unintended acceleration" fiasco
of days gone by. What was it, the Audi 5000?
Anyway, it was determined that in those Audi cases people were
absolutely convinced that they were standing on the brake pedal, but
they were standing on the gas. There was no mechanical problem at all
and it was just lousy ergonomics combined with clueless drivers.

Mostly, but not completely true.

My subaru, the brakes will fight the engine to a draw and get the car
down to 30 or 40 or so, but if I kept at it the brakes would overheat
and I'd lose 'em.

Subaru brakes on some models are known to be marginally sized.

I agree with the sentiment that cars above a certain level of
complexity need a kill switch.

If it doesn't have a simple key that will kill the engine no matter
what, and/or has a complex method or a lockout for neutral,
killswitch.

Strong foot, the instant you realize the throttle is WFO, is still my
plan.  Flicking the beast into neutral is a good idea too but I'm not
convinced I want to take my hands off the bars while doing
this manuever.

As for the 911 call, yep, sounds like he overheated the brakes,
then decided best bet was to call for help.  His cop training
I guess.

Rereading that, it's pretty harsh.  But man, the call is 48 seconds
(that I found online), probably another 15 to dial and be connected,
go through the possibilities.  Brakes, blew that.  Switch it off,
forgot.
Trans to neutral, forgot.  Trans to anything, even reverse, forgot.
Emergency brake, blew that.  Find something soft to hit.  Call the
cops.  He skipped a few steps.


Go fast. Take chances.
