Correct. I worked for 20 years in railway safety and we had a price per life for investment decisions.
Thing is, my life is priceless to me
. Certainly worth more than a few thousand for TCAS (or FLARM, ADS-B in etc). And there's a fair chance it did save my life (previous post). So on my cost-benefit analysis it makes sense.
If I was in a C172 about to do, for example, "unusual attitude" training, with an almost invisible helicopter hovering below me, it would be good to have an electronic Mk2 eyeball to help the human and imperfect Mk1 pair.
