My commute is 9km and I wear bibs mostly because I've never found a saddle that I could ride on for 30 minutes each way, 5 days a week without some sores developing. No issues with bibs though.

Haha well it is central London at rush hour, not the lanes. If you want exact figures, strava tells me 9.2km at 25.8kmh average which I think is fairly good for rush hour central commuting.
