I doubt there's any more of them crashing than Pipers or Cessnas.

You're probably right. But the point is, this is not supposed to
happen to Cirrus airplanes! Because as soon as a pilot gets into
trouble he has the option to pull the chute and save the day. So, if
Cirrus and Cessnas have the same accident rates, it would be proof that
the parachute "rescue" system basically does not work or in other words
does not provide extra safety in real terms.
It's like the section of the road where a pedestrian had been killed
jaywalking. A crossing with lights markings etc. was instituted and
the number of accidents rose immediately. That's because people
crossing were not careful anymore as they were when jaywalking.
