It's always a shock when you pass a glider coming from

I wonder how well you look (ie one looks) out when a little part of
the brain assumes that flarm would have reacted to anything that
mattered?

There is always the problem of adverse compensation when a safety device
is introduced. Monitoring of the situation should continue after the
introduction to ensure the desired increase in safety occurrs. I believe
this is the case with FLARM.

What puzzles me is how skeptical you are about a widely accepted device
you have not used. FLARM has sold 9000 units. 9000! When 9000 pilots
voluntarily equip their aircraft with an $800 device, I am inclined to
think there may be something quite useful there and to look forward to
an opportunity to use one.
