Crash one, I note that your interpretation of soay's post differs from mine.
I'm not sure how you can claim that radar doesn't miss any - there are plenty of non-transponder aircraft out there. There are also lots of people who forget to switch the damn thing on, even.
I relate it to all sorts of things I've heard around various airfields, posts here (and other aviation bulletin boards) that tell me that, contrary to your post, there ARE a lot of pilots out there blundering around, head down looking at their wonderful GPS that will keep them out of controlled airspace even if they don't bother to subscribe to an update service, who think they don't need to look out of the window because they've got TCAS now, who don't even worry about busting VMC minima even when not IMC rated, ears blasted off by having the iPod plugged into their headset, etc. etc.
You may not - there's plenty who do.
Finally, I draw your attention to the TIS-B NOTAM (link in my first post above:-
Pilots flying in visual meteorological conditions (VMC) are reminded that visual contact remains the only means of self separation.
(my emphasis).
