I am one of those who is also skeptical of people who have the ability to dial 911 on their cell phones and talk for many minutes but cannot figure out how to stop their "runaway" vehicle.
However, I have also spent many years designing computerized control systems. I have always been leery about saying "there is nothing wrong with the electronics or software" when troubleshooting MY work. Mainly, because I know that I am human and may have made a mistake that, given the right set of circumstances, could produce an undesirable outcome. Troubleshooting a car built decades ago for a problem like "unintended acceleration" would be easy (accelerator linkage to carb). Today, with ECUs, TCUs, BCUs (computers that control engines, transmissions and bodies (i.e. other car electronics)), it gets more complicated.
I am sure that Toyota uses FMEAs (Failure Mode Effects Analysis) in ALL of their control system designs to prevent just such events. FMEAs are a requirement in ALL automotive companies that I have worked with. These are required of their components as well as the machinery on the factory floor that is used to make the cars. It's basically a "what if, what if, what if" iteration that should identify weak spots in the product/process. If I was Toyota, I'd be pouring over those to see if the designers missed something.

The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
