No, I think it's more a problem with brake fade -- if the driver
rides on the brakes without full force.  It would be better to
just stomp on it and try to get the car to stop asap (let the
ABS deal with any potential wheel lockup).

One thing that bother me, though.  Is that Toyota has issued
recalls and has "fixes" for the supposed problem, but no
Lexus models are covered under any such recalls.  Yet many of the
UA reports are with Lexus (such as with the infamous CHP officer).
The recalls shortens the accelerator pedal (to avoid a
floormat jam) and adds a shim (to avoid a possible stuck pedal),
but no ECU reprogramming.

It is my understanding from the reports that Toyota's drive-by-wire
system does not override the accelerator when the brake is applied.
VAG cars do, I believe, and probably most others...  so this
would be a software issue, but Toyota has not (yet) admitted to
an any software problem with regard to the UA issue.  This
is not to be confused with the separate Prius recall which _is_
software related.

Whatever the real problem is, it's like peeling an onion and
I am sure we haven't heard the last of it yet.
