Toyota already has it too and I am kind of surprised it isn’t universally
used on all models. See: http://www.youtube.com/watch?v=YiSQeaeWxGU

People who want to know how a car should behave if the throttle pedal acts
up electrically need only to do a search for Prius big hand syndrome.  The
NHW11 used a dual potentiometer instead of a hall effect sensor and as with
all potentiometers they eventually get scratchy and fail.  This includes the
NHW11 throttle pedal sensor, the throttle position sensor on most cars and
the mechanical airflow meters used on some vehicles.

… unless the driver panics and continues to press the throttle
instead of the brake.

but there’s no chance that’s the case, right?

All fine and good, but ‘john’ here keeps posting this bile to the toyota
groups. If he were smart, he’d have at Toyota. They have a consumer call
line.

No need…. If they don’t want to program it themselves, Toyota could
just outsource fully functional brake override software from almost any
other carmaker out there. Ford, GM, Chrysler, BMW, Benz, Nissan,
Honda…. They all have it already on their throttle-by-wire cars.

Maybe they don’t have anything left in their pcm’s to handle the
overhead of that programming fix.

God forbid people should know to put it in neutral and use the
‘emergency’ brake.. One of the first things you should do when you
aquire a car (new OR used) is go over the  whole ‘worst case scenario
thing’..  People are in too much of a hurry to do that anymore.  And
in many cases they ended up in a hurry to the funeral home.

Toyota has it, an easy programming fix. Cheap Ass Toyota wants you to
learn how to put er in neutral and pull the emergency brake instead.

This "brake override system" proposed also eliminates the possibility of
the driver intentionally trail-braking, making the cars worthless for
racing.  Of course, we haven’t had the Supra here for years, in any case…

Nobody has. Supra production ended in 1999 (?)

Celica production continues, but not for US sale…  :(

Why don’t you go ahead and design one and send it alnog to Toyota, genius?
