ATC Watcher:
Lateral offset has been discussed here before extensively in tech log, and in ICAO . IFALPA ATS past chairman went on a personal crusade with it but lost. because numbers show that with offset you mathematically increase the collision risk. (check ICAO doc if you want the details and the formulaes)
We can easily assess the result of applying this rule on the highway; My neighbor (bless her soul) drives down the centerline, and all the other cars are off in the ditch!
