That's completely unacceptable, and typical of the 'just me' attitude too often prevalent in Ireland. It's OK for ME to use the cycle path, or the disabled parking spot, or the bus lane because I'm in a hurry, and others can go lump it.
Nothing of the kind. Considering the lack of enforcement of a whole plethora of laws, you expectation of enforcement of pedestrians is completely unrealistic. To be practical, there will be pedestrians on cycle paths especially where they are beside each other. I may wish it to be otherwise, and be vocal about it. But you have cycle with some responsibility, not to cause injury to others.
The cycle lane is clearly marked for cyclists only. Signs have been added recently to show that there should be no walkers on the lane. Anyone who continues to walk on it is being dangerously anti-social, and putting their own safety and safety of others at risk. It's not as if the alternative is a big problem - it's a parallel path about 5 metres away.
If its a big problem, how many deaths and injuries are caused by it.
Did you bother to read the article that you linked to?
Yup. I included it for balance. Its more useful sound bites, so others can get the bigger picture. Of course you can choose to see one side of any story.
Sorry, but cyclists don't 'come out of nowhere'. They usually come from the left side of traffic, filtering beside slow moving cars. If you find that cyclists are 'coming out of nowhere', you need to improve your observation.
Drivers observation certainly needs to be improved, as does there general awareness/expectation of cyclists. On the flip side, some cyclists very much over estimate their visibility and the limits of human situational awareness.
