There's a lot of emphasis on riding "vehicularly", on gaining speed to get past junctions, on training people to avoid common problems. These are fine survival techniques in an environment which is hostile to cyclists, but they are not a way to make cycling a normal means of transport for the masses. Those with a desire to cycle, who are fearless enough and strong enough will continue to do so, while those who are more easily scared away from cycling will never start in such conditions. Cycling needs to be something other than an extreme sport to make the majority of people see it as something for themselves.
On the way home recently I found myself behind a rather elderly gentleman who was making his way slowly through a village near here by bike:

You'll also see how children had met friends on the same cycle path. The infrastructure makes this possible. No-one has to be a "road warrior" to cycle. Parents don't worry about the safety of their children. Older people also see cycling as a perfectly reasonable way to get around.
Compare and contrast with this video made by someone who says "you can ride your kids to school" in Bristol:
It's laudible in that this parent has taken great care in teaching his son to ride so safely as possible given the conditions. In the UK it's quite exceptional for an eight year old to cycle to school, even with a parent "just behind and out a bit to offer some protection and direction if needed". Meanwhile, just over the North Sea here in the Netherlands the average age for a child to go to school unaccompanied is about 8 and a half.
The infrastructure is the reason why. There is a distinct lack of subjective safety on those streets. This is why attempts to train people to cycle are not working. It's also why in the second video you don't see other children cycling to school, older people cycling, nor indeed many other people riding bikes at all.
You're a member of a self selected group
Campaigners often ignore the reasons why they are cyclists while the majority of the population are not. It's very simple, those who cycle now in low cycling countries are by definition members of the easy demographic for cycling, made up largely of enthusiasts and relatively fit young adults, while those who do not cycle are from different demographic groups who are not naturally given to cycling especially if it involves risk.
Cyclists in most countries are an out-group. To change this, it's no good to say that conditions are OK for you. You need to reach the people who are not part of your group and you need to tackle the reasons why other people do not cycle.
Different people have very different needs for safety, and in particular, subjective safety. People who are scared to cycle now, will remain scared to cycle unless conditions are made very much better, to grow the modal share past the usual easy demographics and to include people who are more difficult to attract to cycling requires not just a little more, but for the standard of facilities to increase exponentially.
