It doesn't matter what way you slice this, for a high % of the population, the work commute on a bike just isn't practical for a whole lot of reasons. That's not coming from a 'I don't want to do it' perspective, it's simply a practicality fact. There's still a LONG way to go e.g. public transport infrastructure etc before the masses will leave their cars and jump on a bike.
Digressing slightly, if I drive to work it takes me around 15 mins tops and I have the flexibility to drive anywhere after work should the need arise whether 5 miles or 50 miles away. If I elect to leave the car and take the bus, I've got a change to make and the end to end journey is around 50 mins. Even if I wanted to cycle, see my earlier posts re 7 mile stretch of busy A road. On a bike? No thanks.
