Wedge, all of these are good points. I am an electrical engineer, with a fair amount of software done on machine controls. We would never use software on safety related areas. With multiple processors the rules have changed, but it still scares me. I think car companies are very close to software controlled brakes. I think this can be good, but they better be careful. It's the software controlled steering that I am very concerned about. I expect all of the car companies are taking second looks at this, not jut from the real issues, but now from the consumer perceptions.
Toyota may already have figured out the problem (if it exist), but they may be keeping quiet until they have a manageable (i.e. cheap, simple, easy to implement, and parts available) solution. Most people don't really understand what it takes to retrofit 8 million vehicles, with relatively untrained (for the change that is) personnel. Also the fixes they are now putting in probably cause more problems than the next problem. So they want to finish those first.
Ditto Bob.. I work as a gov. eng and I've been working on a pretty complicated system for the last ten years. I dont do software, but I'm very aware of the testing that needs to be done if/when anything is changed.
Obsolescence is a gold mine in the Gov.
Oh I forgot to mention one thing.. When I was figuring out how put the Pruis in neutral. I did find something interesting. Once IN neutral the engine RPMs would drop to idle for self preservation. Found that interesting also.
