Simple. As soon as you leave the Netherlands, all of the worlds town planners want you dead if you take any interest in travelling from place to place in a way which involves getting exercise and not releasing horrible pollutants into the atmosphere. Riding on the pavement is often anti-social, unless of course the pavement is easily wide enough for pedestrians and cyclists to pass with plenty of space inbetween, and as a result many, if not most, jurisdictions take the slightly over the top move of making cycling on the pavement illegal...
Yes, cyclists should not be cycling in the road, but if all of the people involved in town planning in an area are too cheap, lazy, and stupid to put proper dedicated cycle paths in, then those who still choose to cycle are forced to and everyone has to suffer as a result.
People are put off of cycling by the fact that they have to face the dangers of riding in the road, which also causes a nuisance for drivers when cyclists are in the road, and also, of course, leads to far more people driving rather than cycling, leading to a far higher proportion of roads being clogged up with traffic jams, releasing pollution which everybody in the area has to breathe in, as well as contributing to the build up of greenhouse gases in the atmosphere. Sitting stationary in said traffic jams also, of course, costs drivers money in wasted fuel. Pedestrians also benefit from the implementation of dedicated cycle paths, as it provides another layer of protection between them and the road, reducing the chances of them being run over.
Don't believe me? Feel free to come to the Netherlands. You will be enlightened.
