OMG you are really serious.
This is the Private flying forum and we are talking gliders & GA type aircraft flying low level in uncontrolled airspace.
There are no gliders in class A where I flew before retirement.
When flying a GA aeroplane in uncontrolled airspace.
"The only sure way I can safely avoid the risk of a midair with a glider is not to fly when the gliders are flying."
That does not imply that I won't fly, but the flight safety risk cannot be quantified and planned for as in CAS.
My main point which seems to have escaped you is the possibility of a technical fix for this.
