Boris Johnson has admitted that his plans won't become a reality without the cooperation of local and central government.
"I do not control the vast majority of London’s roads, so many of the improvements I seek will take time. They will depend on the cooperation of others, such as the boroughs, Royal Parks, Network Rail and central government.
"I do not promise perfection; I do not promise that London, a very different city from Amsterdam or Copenhagen, will quickly come to resemble those places. But what I do say is that this document marks a profound shift in my ambitions and intentions for the bicycle in London."
