It's a cycling board, which suggests a certain advocacy of the transport mode in question. If it were an agreeable cities board, or a Transport 2000 thread or Petrolheads or some other lobby one might expect differing opinions on the viability of the bicycle as transport, but it isn't. Bicycles work for all kinds of chores from taking the kids to school to doing the shopping. Why should city dwellers be singled out to pursue those choices in safety?
Now what would make you think that? yes it's a cycling board, it's also a discussion board, yes most of us cycle but it doesn't follow that we think everyone should cycle and that it would be some sort of utopian future. Also, who said anything about singling out city dwellers, I'm not a city dweller. You make too many assumptions and come across in an evangelical manner, this is pointless with existing cyclists and will be off putting for a lot of non-cyclists.
Tackling the car as the default, or highly desirable, first option is far more in keeping with my way of thinking. Cycling infrastructure is spitting in the ocean against that. Think of all the other things that can make inroads and already exist or are being campaigned for:-
home working and localised office solutions
internet shopping and home delivery
public transport
peak oil
local businesses
regulation to make corporations shoulder a far fairer %age of externalised costs
school buses, walking buses, cycle to school schemes
parking restrictions and tax on parking spaces
planning priority away from cars and sensible housing programmes
costs of running a car, toll roads to put some of the cost burden back on the main users
I could go on but I'm sure the gist is there, please don't jump on a board, make a mass assumption about the existing users viewpoints and then start preaching.
