Charles, I have seen what the "BSOD" can do to a computer contrllled industrial testing machine, (NOT of my design), and the damage was not minor.
The comments about updates and hackers are also certainly valid, and they do bring up whole additional realms of reasons to approach the implementation with caution.
My prediction is that if the autonomous vehicles are ever mandated that traffic speeds will be reduced to the point that any collision would not cause injury, since the vehicles will be moving so slowly. While that mode could be safer, I don't expect that many would find it acceptable. The entire exercise will turn out to have been a large waste of money, materials, and time. And only 80% of the folks will realize it.
Multiple reasons exist as to why the autonomous car willnever work. Not that they won't be made and sold, but that the promised benefits will never happen. First is the legal problem, since when there is an accident with injury somebody will be at fault, and that would be the producer of the control program that was doing the driving. The auto companies won't accept that, as Charles has already explained. And he is right. The second challenge will pop up even sooner, which is that when an exception situation happens the car will not know how to deal with it and so it will just stop. And we know that exceptions will happen. That will make them very unpopular in a real hurry. Or they will make a wrong choice,with a similar result. The automotive equivalent of the dreadd "blue screen of death" will be te end of the driverless vehicles on public roads.
The Toyota case is definitely a concern, Cadman-LT, especially when you place it in the context of the autonomous car. Software expert Michael Barr, whose testimony turned one of the recent Toyota trials, had a lot to say on that subject at EE Live this year:
I love the fact that the google cars have no steering wheel or pedals. So when it screws up I guess off the cliff you go! No way would I trust a car that I couldn't at least correct at some point. Well, at least it only goes 25mph, you'll probably survive if you have to bail!
I have a hard time with the whole concept...as much as I like the idea. I just think back, and not long ago, where Toyota had braking and I believe gas pedal issues. I just think it has a very very long way to go before I trust an auto car. If they can't get the basics right....I mean really. And Toyota has been doing it a lot longer than google.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
