RR,
I read IO540's diatribe on the other thread and felt that it would be wrong to post such a diametrically opposed view on that thread, so I do applaud you for starting a fresh one.
I'm just a very simple bloke who flies older technology machinery (day VFR) . I hold an aerobatic DA and I fly well over a hundred hours a year.
Without a doubt I spend most of my time looking out as I've got bugger all else to look in at and worry/fiddle with.
A few pilots (household names in the seventies) have died over the past few weeks, men with thousands and thousands of hours - they have all expired far away from aircraft crashes and midairs.
I do not think that TCAS(D) will make that much difference (affordablity, reliabilty), how many terminal mid-airs have we had in the UK in the past 20 years ?- I can think of only a handful.
Address the root cause not the symptoms and addres it with training not with placebic tools whose reliability (PDA at £100) is questionable. It is a £ucking big sky out there, use it sensibly - LARS, flight info, etc., but let's not force the powers that be to over regulate us.
How many folk died on the roads on Sunday?
