Get on a bike. To be honest, I’m not much earlier to work than if I set off for the bus at the same time, my time saving is on the journey back. But if I set off five minutes later I’m only five minutes later by bike whereas I’m anything up to twenty minutes later by bus because of the rate at which traffic density increases.
