Good one! You must be looking in the mirror... you're the one obsessed, not me. I'm quite happy with the current, risk-graduated system we have at the moment. More ADS-B and transponders in the future will be even better. Bit like the 406 beacons: technology that replaces VHF radio and all that other worry about who is going to hear me and find me when the noise stops. Don't even need a flightplan!
