Do you have a cite for your statement that motorists are more careful around cyclist that are not wearing helmets and less near those without?

Even if you don't share this belief, the analogous question is still relevant:

the question is whether the change in pilot behavior with PFLARM is, looking at the whole picture, more or less safe.

In the context where only some pilots have PFLARM, I'd fly as if no pilots had PFLARM.

So how do you fly now? Do YOU have FLARM?

I'll leave that unanswered because whether I have FLARM or not does not make my question any less valid. I will admit that I'm very glad to fly with a Trig Mode-S transponder.

Everybody agrees that 'complacent' is bad. The word complacent does not capture the gradations of vigilance. I'll admit that I'm somewhat less vigilant about traffic when I'm more than 5 miles from the airport and somewhat more vigilant when I'm within 5 miles of the airport.
