As Easy As Riding A Bike

It might be that other countries such as the Netherlands have already gone through that cultural change and so were able to the cycling infrastructure you would like.
The above (from page 9 here) shows 20th c. modal share for the bicycle in a number Dutch cities (alongside Basel and Eindhoven), with Manchester (the blue line at the bottom).
We see massive decline across the board from 1950 onwards. The decline was arrested, and reversed, in the early 1970s, in the four Dutch cities included on the graph - this was precisely the period when the Dutch started building safe segregated infrastructure, and removing the car-centric layouts of their towns and cities.
I would argue that the 'cultural change' you speak of is a consequence of that infrastructure, not the other way around. Getting more people on bikes results in an attitudinal shift towards the bicycle, especially when driving around people on them - because you are likely to know what it is like to ride one. I would suggest that in the UK most bad driving towards cyclists is perpetrated by people who go nowhere near a bicycle for everyday activities.
Without the infrastructure, it is likely the decline would have continued, as it did in Manchester.
