This added after reading GRC's post above: I though I read something about a cable sticking possibly due to moisture / corrosion ? ? ? Guess even in TBW there eventually has to be some sort of cable to actuate the throttle ? ? ? In any case it is a bad situation for all concerned.
The pedal assembly for a throttle by wire model still has a pivot, a linkage attached to the sensors, return springs, etc., but no cable. The story I read that quoted the guy from CTS indicated that an engineering change was made by Toyota to fix a different problem, and now moisture can get into an area that can lead to corrosion and increased pedal effort / sticking. If that is the case, I would think the sticking or increased effort problem would be something that would give a driver advance notice as the corrosion formed, and wouldn't be the sudden and catastrophic problem that has led to the wide open throttle crashes. In other words, this is probably
a problem, but not necessarily
the problem. I guess time will tell. In the meantime, I'll stick to driving my Ford products.

One thing about this whole issue that really bothers me is why the driver's of the vehicles don't understand how to deal with a stuck throttle. There are two methods, put the trans in neutral or shut off the ignition. Just standing on the brakes isn't going to do anything good; any auto engine can easily overpower the brakes. For some reason I always thought the average person knew these things, but obviously lots of people don't learn much about their vehicles other than how to turn them on and go.
