The point cycletourist makes is pertinent. If the people who plan cycle facilities and traffic policy regard cycling as only a sport, what they provide are leisure facilities, not transport facilities.

This is not to detract from the sporting aspects, just to bear in mind that you can use a bike for getting to work and doing the shopping. I cant thing of any definition of the word Sport which describes me doing the weekly grocery shopping.

Toys are things you play with, and if you do your playing with a bike, its a (expensive and sophisticted) toy. If you do your shopping on a bike, its a (generally cheap and unsophisticated) vehicle.
Toys are not tools, and you can see that by comparing any hardcore commuters bike to a sport bike. Skis (xc, not alpine downhill) can be tools, for people who live and travel in snowy regions, but what is the job for which snowboards are the right tool ?
The policy makers generally regard bikes as toys for leisure, not vehicles for transport.
