Which Toyota is doing. But that doesn't affect pedal misapplication if only ONE pedal is depressed. That situation covers the overwhleming majority of SUA incidents. > The shift interlocks that force you to press > on the brakes before shifting into gear were a "fix" for the Audi 5000 > UA concerns.

And somebody, somewhere, will still find a way to make a car run away with itself anyway. At some point you have to give SOME sort of control to the driver. and ANY sort of control of ANY kind carries SOME degree of risk. Life is dangerous. And it's imperfect. And it is risky. At some point you have to accept those facts, be your own last line of defense, and stop blaming others. -- Tegger

I believe the accelerators for Europe were sourced from CTS as well.

I don't get where he said that. A lot of people are pointing to the electronics, but since the affliction spans a lot of models, electronics seems out of the picture.

That's what I get for listening to NBC News.

It's chassis is a modified version of the old Mazda 626 from when Ford had a large share in Mazda. It's also used in the Mazda Tribute. They are both made on the same assembly line, although very few parts are interchangeable. Bob |
