Simon T,
"If I am in the air I use a radio and a transponder. That helps me stay safe and helps others to know where I am and what I am doing and stay safe as well."
How does that work? You have a transponder, I have a transponder, but I still don't know where you are!
Regarding the radio, we are in Class G airspace North of Luton. I'm talking to London Information, You are talking to say Cranfield as you are near. How does the fact that we are both using radio help?
Both aids may give a false sense of security when only a good lookout may save you. If you want a useful aid then consider FLARM!
Why shouldn't I expect anyone else who is in the air to do the same? If it's too difficult (following; Aviate, navigate, communicate) for some they need training, if it is still too difficult they need to find another hobby.
I think Heston said it all...
