Another unintended acceleration...

I'm not sure if that contraption was presented on a 2006 model though. And I'm not sure how it works - does it work by applying brakes or does it work by applying gas a little?

Incline assist works by holding the brakes until you press the throttle. I'm pretty sure all 2006+ cars had it; the one I drove did, but it had the correct good manual transmission; I'm not sure about the ones with wrong bad automatic transmissions.

Cruise control in this car is handled by the ECU. There's no mechanical system to adjust.
 
German cars tend to have pedals that are close together, and can be hard to drive with work boots. Ask me how I know I almost put an S class in the mud because of some steel toes, I'm a size 12.
 
My little size 10 feet are a bit smaller than most guys complaining about BMWs here. The only cars I just can't drive without taking my boots off are a few Jaguars, the second generation MR2, and the Chevy G Van.
 
I wear an 11 and have no issues

I almost always take my shoes off to drive. My feet are too big in most shoes to drive well.

My wife drives in flip flops!?!?!

In the late 80's I worked in a tire shop and almost drove a 560SL off the end of the alignment rack. Only time I ever had an issue like that, and first time I experienced a strong (at the time) German V8. I gained new respect for a few things that day.
 
The Audi 5000 series had a similar problem with pedals being too close. My Audi 200 had them a bit further apart, and staggered, with the brake pedal being much higher than the accelerator. Audi definitely suffered from the stories back in the day.
 
the only car I ever had a problem with was my brother-in-law's Barracuda. The 273 and the Torqueflite were replaced with a 340 and 4-speed but the wide automatic brake pedal remains. I bumped brake pedal a time or two while pressing the clutch.

oops!
 
"Unattended acceleration"

Actually it usually is a mechanical problem:

A loose nut behind the wheel?

Cheers!

Yep.

I had a similar experience, back before racing on public streets was such a no-no, I was in an automatic supercharged oldsmobile racing some guy in something else, I don't remember what. I was used to driving manual cars. Hand on the shifter, Redline in first gear, I let off the gas slightly and slammed the clutch to the floor - except it wasn't the clutch, it was the triple wide brake pedal.

Oops. luckily we had our seatbelts on. Needless to say, we lost.
 
This happens to me in my truck. When not paying absolute attention sometimes the gas pedal is pressed witht he brake. It can get pretty exciting if there are cars in front of me, or a busy cross street.

It doesn't happen in my other vehicles, only the truck. And not all the time but just when I'm sitting just right and all the angles are correct for a 1"-to-the-right approach.

Operator error.
 
I've spent the majority of my life in manuals, the Caprice is an auto.

Driving home fatigued last night, was stuck at road works, and was creeping towards car in front. Pressed harder on the brake, and heard more roaring up front and more movement.

Manual would have just dipped the clutch, auto I had to mentally take control, take foot off pedal, accept THAT forward movement, and grab the brake again...US size 8 steelcaps.

I can see how a flustered person (rather than simply brain dead tired) could push harder and run over their daughter feeding the meter (like happened to our neighbour when I was a kid).

Peeling out on the alignment machine... Nicely done!


Gotta remember that next time I go in for an Alignment.

Newer Fords have a safety function called "Brake over Accelerator". If both pedals are pushed at the same time or if the accelerator is stuck down, applying the brake causes the ECU reduce the electronic throttle so the brakes can stop the car and hold it still.

It's kind of an electronic version of really big leg muscles and good brakes.

Motor Trend performed an interesting "sudden acceleration" test as part of their midsize family sedan comparison testing in 2011:

http://www.motortrend.com/roadtests/seda...on/viewall.html

They tested 60-0 braking with 0% throttle (typical braking test), but also measured 60-0 braking with 100% throttle (trying to approximate a stuck floor mat or similar, since that was big in the news at the time). Of the seven cars tested, only the Fusion and Malibu posted significantly different braking numbers with the throttle applied vs. with the throttle closed. In the case of the Fusion, it took an additional 37 feet to stop with the throttle at 100% (the Malibu needed an additional 30 feet). The other contenders (Accord, Sonata, Altima, Legacy, Camry) all posted braking distance differences of 4 feet or less.

It's clear that the brake override technology included in modern cars can significantly change the outcome of an event where the throttle pedal is depressed (or if the car THINKS it is depressed). All vehicles with DBW should have this, if they don't already.
 
My 2 '06 Infiniti's (Nissans) lower power output to about 30% anytime the brake lights are on.

Even if the brake lights come on due to a short in the trailer wiring between the turn signal and the brake light. The throttle would close with every blink of the right turn signal.

That was an interesting trip.
 
I don't think my 2011 Focus has that override feature ... I"m able to heel toe fine with it ... well as good as you can on something that has electronic throttle.

Then again, Ford probably figured that folks driving manual would just push the clutch if it runs awat
