My own personal view is that cycle tracks/paths/lanes should not be mandatory and that a degree of common sense should prevail. Like when you approach a green light in a car your right of way is not absolute and you should proceed with caution. For example, you should be prepared to stop in order to prevent an accident or to avoid a pedestrian. Similarly, in cycle paths/tracks/lanes (including mandatory ones) a cyclist should be allowed to leave the cycle lane where it would be dangerous to use it or to avoid a parked car, people walking, etc. i.e. being mandatory is not absolute.
You have to consider the sources of information - one is a biased article and the other is the legislation. I know which source I would believe.
This thread is about whether cycle lanes/paths/tracks are compulsory and my view is that they are only mandatory where the three signs are provided and this may or may not be contra-flow or pedestrian areas. It could for example be on a road. Saying that the only mandatory cycle tracks are in pedestrian areas or contra-flow lanes is not correct.
This is the consolidated Act which contains all of the Amendments made by S.I.s over the years -

The definition of a cycle track in paragraph 14(1) of this Act states that a cycle track is indicated by signs RUS009, RUS058 and RUS059. In paragraph 14(4) it states that a cycle track may be on a road, portion of a road, pedestrian area or contra-flow lane. That's how I have reasoned it and come to my conclusions.
Examples of the signs are available in section 5 of this document -

I'm glad to see that the RSA (an agency of the Dept. of Transport) have finally changed the Rules of the Road to say that "Cyclists should wherever possible use any cycle track provided." at the top of page 201. Previously it stated that cyclists
must use any cycle track provided.
