Do Not put your leg down.... Your right to question if it's safe, because it's not safe. You are more likely to break your leg than save the bike if things get wierd. Only dirt track and motocross riders use that technique, mostly because they are sliding sideways.
That was a great video. Sometimes I wish we had a proper Touring Scooter Club here in NorCal, almost all the time it's just me and the missus out on the open road. All by ourselves.
