Now, the inevitable analogy:

When antilock brake systems for automobiles first began achieving widespread
market penetration, the number of accidents involving police cars increased
dramatically. There were three primary reasons for this:

Exposure - Police officers drive a lot, and much of it is stop and go
driving.

Conditions - Police officers frequently drive at high speeds, which require
"hard stops". And they frequently drive on roads in less than optimal
conditions (maintenance, weather, etc.).

Training - Police officers were trained to "pump" the brakes, a technique
that causes ABS to work with even less efficiency than conventional brakes.

So, police departments implemented re-training programs that taught the
officers both to apply steady pressure to the brake pedal, and helped them
break their old pattern of pumping the brakes.

The accident rate returned to close to previous levels.


Yes, it's a great analogy. A supposed safety advance was introduced
into the cars. After retraining, the result was almost as safe (not
safer) as what it replaced, and more expensive to boot. Without
retraining, it was a lot more dangerous. What was the advantage
again?

And this is analogous to the Cirrus situation. It requires retraining, but
given the proper training it's not an especially dangerous aircraft...


But it's supposed to be a safer aircraft than what we fly. It was
supposedly designed for safety. Now we think that maybe with
sufficient retraining it won't be especially dangerous.
