One man started it, with support from County Councils willing to support the idea.I believe in Ireland the distances between bike and overtaking car is promoted to leave 1 metre on <40mph roads and 1.5 metres on >40mph roads.
There is an interesting programme on Irish TV channel RTE1 called 'Now You See Me' about increasing cycling infrastructure, provision, safety and increasing active travel across all demographics in Ireland, which is where I got the above from (if I'm remembering correctly, apologies if not).
