Time to get real and standardize what we are doing in the aviation
community.
Radios. Person to person communication. Not perfect but a heck of a
lot better than some pilot trying to decide what the tow plane is
doing.
Radios. Transponders. Flarm if you want to add one more layer but
NOT a substitution for a transponder.
That is my take.
Flying is expensive. Get over it. Buy the equipment. Batteries are
no longer an excuse.
We are not hang gliders jumping off some cliff.
We are sharing a crowded and complex airspace and airport with all
kinds of traffic.
