Craig - you may be right, the guy may be a shill for Audi (or Toyota) - but
he made a surprising amount of sense to me (and I'm not uncritical of
Psychology).

Assuming he's on the level with the research (if not, he can prove anything
;-), he has one very compelling argument. To me, the biggest argument for
the validity of the 1980's Audi analysis is the disappearance of the problem
when Audi invented the brake pedal / transmission interlock switch. 

That is the sort of solution that really appeals to me. Make people step on
the correct pedal before they can engage a gear to drive away and suddenly
all the scary Audi stories stop... All the run-away Audi accelerators
magically stop running away with people - because the people are forced to
do it correctly. 

Humans make mistakes. They are also very resistant to the idea that they can
make mistakes. A quick look at the history of table saws - which are mostly
free of software - will demonstrate both those principles pretty well. There
are lots of missing digits and lots of missing blade guards (removed by the
operators).

If you want to make a machine safe - the hardest part is idiot-proofing it.
Software errors are much, much easier to get right. 

I say that after many years of work with machinery, small computers and
designing what we used to call 'the man-machine interface' - to draw on for
all the examples you could ask for.

So Dr Schmidt may well be extrapolating incorrectly into 2010 - I've no
proof either way. If I had to bet, I'd probably put my money on him rather
than on the quality of analysis of our modern hyped-up media... I also don't
believe in the infallibility of California State Police officers - hell,
even aircraft captains get it wrong from time to time and the selection &
training processes they face are somewhat more careful.
