As much as I don't agree with the aggressive tone of the grand-parent post, I tend to find it less a problem outside the urban areas due to the bike roads in the "countryside" more available either in Belgium or the Netherlands. It is also the part of the countries when the need of a car is enhanced due the need to travel way longer distances to reach day-to-day facilities (supermarket, shops, etc.).

And yes, different countries, different prices, requirements etc. Comparison is fallacious but taking inspiration of something done in another part of the world and applying it with the constraints of your own environment is always useful.

The question of mobility is much centred around the mobility in urban areas of various sizes. I may project here because I used to live in urban areas most of my life.
