The lack of dedicated lanes was mentioned already. But this alone, while significant, is not the biggest problem with the bike. Let's take Toronto. I could probably bike to work 9 km in an hour (half an hour if I had a dedicated lane - but I don't). However, in summer I sweat a lot and there are no showers at work. In other seasons - it is rain and snow that are the obstacle.
