How does cruise control work into this? This has been a problem area on past cars.

and all 3 engines us a throttle cable which I dont see how it could be hung up, I have a 4.7 in my Jeep.
This is another Media Drive by story where the reporters are too lazy get facts, but then again most news people are pretty stupid when it comes to anything automotive. You would think they could at least get the make and model and maybe the engine correct, but that takes an ounce of brains to ask that kind of question whe creating a report!
They switched to DBW somewhere in the middle of that generation. My 08 was DBW.

Had this happen to me in another car. Floored it at the light and the throttle got hung up and the engine was stuck at 4k rpm. Took me about 1 second to realize this as the car wasn't really slowing down that much. I just popped it into neutral and was able to stop the car and didn't hit anything or anyone. It was later recalled for a bad cruise control cable.
^ And what car was that?

It certainly is easy to play the armchair quarterback. Without actually being there and knowing everything that happened, I'm impressed that you have knowledge of the entire situation and are able to pass judgement before the authorities are even finished with the investigation.
Agree. The likely panicked driver went a good distance in vehicle(100 yards) before hitting the wall. It could have been as simply and stupid as floor mat and stuck pedal.

There's a connection between old people and these incidents. We hear about one a month. They run into buildings and kill people quite regularly.

The driver freaked and froze up. Reminds me of when I was in jr high school. My best friend had this super powerful souped up mini bike,and the throttle tended to stick. All you had to do is hit the kill switch to shut it off. One of our other friends hopped on it to take it for a spin around the back yard. He floored it full throttle,the throttle stuck and he had this HUGE "oh sheet!!" look on his face haha and he crashed through the backyard wooden fence,we were laughing so hard we were crying!!

Yup. There was one recently here that piled into a building, went straight out of the Burger King across the road IIRC, through a parking lot and into the accessibility place attached to Shoppers Drug Mart. Was a 1/2 ton and did a pile of damage.

look at his pig 5hit driving record, this isnt some old guy, its an incompetant driver with suspended liscense who happens to be old!
I wouldnt want to be the owner of that auto auction who hired someone with no licsense to shuttle cars, obviously they did no background check, guy cant drive!

Ford Taurus
October 24, 2012 NHTSA ACTION NUMBER: PE12033Speed control cable damage
NHTSA Action Number: PE12033
Components VEHICLE SPEED CONTROL
Opened From: October 24, 2012–June 26, 2013
Summary
On June 21, 2013, Ford initiated Customer Satisfaction Program 13B04 to address a concern with Speed Control Cable damage in certain model year (MY) 2000 through 2003 Taurus and Sable vehicles equipped with 3.0L 4V Duratec engines and built at the Chicago assembly plant. In the dealer letter for the program, Ford indicates that the Speed Control Cables on affected vehicles may be susceptible to damage or becoming partially disconnected during under hood vehicle maintenance (e.g., replacing a battery or changing the air filter) and that a damaged Speed Control Cable could interfere with the throttle's full return to idle when the accelerator pedal is released. Ford's program instructs dealers to inspect the Speed Control Cables and replace any with any portion of either collar retention tab missing. Dealers will install a Collar Reinforcement Clip at the Speed Control Cable collar in all vehicles.
Figure 1 shows the location of the Speed Control Cable in the engine compartment and the proximity of the battery and air filter. The failure mode of the cable assembly is associated with the plastic collar used to secure the cable to a bracket near the throttle body (Figure 2). Damage to one or both retention tabs used to secure the cable ferrule within the collar may allow the ferrule to become disconnected from the collar when the throttle is opened during accelerator pedal application. Additional examples of Speed Control Cables with damaged collar retention tabs and partial ferrule displacement are shown in Figures 3 through 5. If the displacement pulls the ferrule completely out of the collar, the ferrule end may contact the face of the collar when the accelerator pedal is released and the throttle is returning to idle (Figure 6). This results in a throttle stuck at approximately 26-29% open. Testing conducted at NHTSA's Vehicle Research and Test Center found that brake booster vacuum may become depleted, resulting in reduced brake effectiveness, if the brake is applied repeatedly when the throttle is stuck at this position.
Drivers who experienced this condition have reported being surprised that the engine speed did not drop as expected and in some cases misjudged the degree of braking required to slow the vehicle. Some drivers reported difficulty in braking the vehicle and responded by shifting to neutral or turning the engine off. One minor crash occurred when the vehicle contacted a roadside fence post after the driver responded to the stuck throttle by shifting the car to neutral, turning the engine off and coasting to the side of a roadway with no shoulder, resulting in approximately $400 damage to the vehicle. There were four crashes reported which were attributed to increased stopping distance caused by the increased engine power and/or reduced brake effectiveness, including two of the complaints to ODI. In one crash reported to ODI (VOQ 10516101), the subject vehicle allegedly hit the back end of a truck at approximately 40 mph causing about $2000 damage. In the other crash complaint to ODI (VOQ 10501834), the subject vehicle side-swiped a vehicle as the driver was unable to stop in time and attempted to maneuver around a line of vehicles stopped at a traffic light. When the tow truck driver subsequently started the incident vehicle, the engine was still racing and it was verified that the Speed Control Cable ferrule was stuck on the collar. After further investigation, ODI does not consider the crashes reported in VOQs 10456249 and 10159399 to be related to the Speed Control Cable problem.

The problem with the Jeep Cherokee and the Grand Cherokee was that they have a very large driveline hump. Because of this the foot pedals are offset to the left, causing people to think they have their foot on the brake when in reality it's on the accelerator. In my opinion all but a very tiny percent of unintended acceleration is the driver pushing the accelerator while thinking they're pushing the brake.
